Thanks for contacting support. To confirm are you receiving a message stated "workspace in use or corrupt" when attempting to export your PCB or save a workspace? If possible, please try either:
1. Are there multiple instances FAB 3000 running at the same time. If yes, limit to one and see if that helps.
2. Are you saving onto a network or a special folder with unicode characters?
If yes, try using the setting "Perform File Buffering for Unicode/Network Access".
Note: When searching the FAB 3000 source, I couldn't find any message that states "workspace in use or corrupted". If my suggestions above did not help, could you send me a screen capture of the error message.
Thanks again, and I look forward to hearing from you.
Thanks. That resolved the issue.
The export pcb does not show the layers to chose "workspace in use or corrupted"
