Program opens then quickly closes.

[Advall]

Message in the bottom corner says it is parsing saved file model3.stl.

I have deleted all the sample model files and also de installed and reinstalled the program but same problem and message persists.

Any help is appreciated.

The savedstate factory file is likely whats either corrupted or inaccessible.
