Image type not supported?!?

[jackaboo422]

When I try to trace ANY .jpeg file in SCAL2 it tells me that the image type is not supported. Everything worked fine for a long time and suddenly it just doesn't work anymore, I've uninstalled and reinstalled the program and it's still doing the same thing!

Has anyone else had this problem and what can I do to fix it?

Thanks for any help you can give me.
