That's possibly the longest sentence ever, and difficult to understand.
When you say, "i can import a video right from the start", do you mean you can't
import a video from the start? If so, what format is the video you are working with, and what application is it coming from?
"There are no laser presets"... indicating that the other presets are installed and useable, and ljust the laser engine presets are missing? Are the grading presets and the presets for the other engines installed and working properly?
"i removed it from my computer"... context would indicate that you removed the laser, or the scroll bar, but I assume you mean the program? If so, did you follow the instructions for a clean re-install
, or did you just delete the program and re-install? Have you tried importing any presets for the Laser engine? And you mention EffectsLab in your post, but have asked this question in the VisionLab forum; it is actually EffectsLab that you are working with, right?
