Unknown document version (0.0)

My File crashed and says. "Floor plan can not be opened". If i want to open and repair the file and "unknown document version (0.0)" shows up.

Does anybody know how to Fix it or recover a saved version?

i think it happened to be once when the power went down the moment the file was saving. there was no way to recover from that i'm afraid.

Looks like you are in a similar situation. Have you tried opening the bpn file?

Have you also tried the "Open & Repair selected file" option in the Open Dialog?
