How to animate fireball [ANSWER]

I had a trial version which had a box for setting the exact position for some FX, but I bought the pro and this box does not appear.
I am trying to adjust the height and trajectory of a fireball hitting the city of Baltimore. The help files aren't exactly very helpful and the problem is the object comes from top right to lower left.
I want it to come from lower center to mid center, or possibly from top left to middle center of frame. Can anyone help me on this?

im not quite sure what exactly the program is doing and what exactly it is you want it to do.
From what you wrote, I gather that you want the object to travel from the lower center of the frame to the center of the frame. this should be as easy as setting the possition (in the animation tab) for the first frame (lower center) and then setting it on the frame you want it to be in the center.
the problem may be that you animated it differently by accident and you still have old keyframe data changing the course of your object. the keyframes are located in the grid on the timeline, and are represented by white rectangles. find the keyframes that you dont want (the ones giving the wrong object position), right-click them, and delete them.
Its possible that it would be easier just to delete the fireball, and then add it again, getting rid of ALL keyframe data. to do this, right-click the fireball on the timeline, and then click delete. then drag it onto the canvas from the media browser.
Again, I may have totally misunderstood you problem, but I hope i got it right.
If this didn't answer your question, feel free to contact me directly via PM.

Yes I too don't understand what you're trying to say, can you post a screenshot of what you can see on the screen or something?

When I get home from work I will try and post a screenshot.
However, I did a shot of Baltimore's skyline from Federal hill park which overlooks the harbor. I have a couple walking by the frame and just as they pass the middle of the camera angle I want this fireball (which may later become a missle) to come from the upper left of the screen (Canvas) and aim to the center of the canvas which would be the Sherton Renaissance Hotel. When it gets to the hotel I wanna switch to the explosion effect.
My problem is, the preset fire ball comes from the top right of the screen, goes through the center and exits bottom left, which would make it look like it is moving away from the city. I played with this for a few hours and couldn't get it to budge. Now when I downloaded the trial version (non Pro) it had a little box pop on the canvas that allowed me to position whatever effects I wanted. The pro version doesn't have that, or if it does I can't find it.
So my question really is, where is the positioning box, I guess you guys would call it the motion guide (????)

on the timeline, you will see a little blue bar named "fireball" (or whatever the person who made that preset named it). It already has keyframe data because the person who made the preset wanted it to move a certain way.
Click the little arrow next to the name. it should drop down giving you several options. One, is animate. Click animate. You now have that box you spoke of. Now, along the row of boxes next to the things under animte (quad, scale, etc) you need to delete all the keyframes. I think you can just left-click and drag a box around then, then either press backspace or right-click one of them and click delete. somthing along those lines. later today, when i can check in effectslab, ill tell you for sure (unless someone posts before me).

Thanks for the help.
I like this program for ease of use (Based on the trial of the non Pro Version) I guess I just have to get used to the pro version a bit.
I appreciate all the help I can get, I am trying to meet a May15th deadline for a film fest and not all principal photography is finished, so I am editing and now doing Visual FX on the fly.
For a while I thought blowing up Baltimore would be hard, guess I was wrong. =)
It is cool that VFX can be affordable even for low bduget stuff.
