Hi, Im at a loss here.

I have been trying to set a thumbnail that will show as the mod picture when i publish.

I snap the thumbnail and the png is created.
but when i try to pick it i get a critical error.
I can see and look at the png outside of the editor, the file is created but as soon as i try to pick it it dissapears from the folder.
Does anyone know how to fix this?

log is as follows:

Code: CRITICAL ERROR!
Unhandled exception!
