Storyboard Pro 7 Constantly Not Responding

SBP 7 was working on my PC the other night without any issue, but when I opened the project I was working on the other night the drawing lines were not lining up with the cursor. So I closed the program and restarted it only for it constantly say “Not Responding.” The project file is very small at only 35mbs.

I’ve tried reinstalling the program to no avail, I’ve tried to create an entirely new project to see if it would work only for the same thing to happen.

I have no idea what is causing this issue. 2 months ago I was using the program heavily and there was no issues. Is there any way to troubleshoot this?
