I wanted to save my pcb changes to a different pcb file so I used the "save as" menu option. After saving it the original and the copied .pcb files seem to be corrupted.
When I try to open them DesignSpark throws the error: Unexpected file format...
Im using Designspark 8.1.
I've installed Designspark 9.0 to check if I could open the project with no luck.
