Hello!
You installed the new version, not the older version (3.0.1), correct?
Did you change any export settings?
Try running the app as administrator (right-click the app -> Run as Administrator) and then export again.

Sorry yes I did do I all those things but I managed to solve my issue. I'm very new to creating Spritesheets so I didn't really know how many frames where average. The program kept crashing because I was trying to export 900+ frames into one Spritesheet. I'm an idiot lol
Edit : Thank you for replying so quick though.
