I have been battling with this issue for about a week now. When I tried to open one of my saved projects it kept saying "unable to read the project file. The project file may be invalid or corrupt." At first is was just one project it wouldn't open (which had a lot of work in there) but now it's like 3 or 4 different projects that it won't open. I checked the name of the file to make sure there were no special characters, I made sure that they were saved as a scut3 file and I made sure they were all defaulted to open with sure cuts a lot. I'm not sure what else to do. Thank you

Are you trying to open the files by clicking on them or opening them from the program?

No. I first open the program then choose open project... i think that's what it is im not at my computer right now. But then I go to my projects folder and choose the file I want to open

Also I have a question. When I go to save my projects theres two different options in the drop down menu. I attached a picture. Could someone explain the difference to me. Thank you.

If you save the project it will become a "scut" file and you will use the open command. If you export as an svg then you would use the svg button not the open file.
