Please help! How to solve :

An internal error occurred during: "Finding occurrences".

Can't do anything anymore. Tried everything, updated AIR, delete workspace etc.

Ok lol once I post I find the solution...

I delete the project without deleting the files. Then recreated the project at the same location.
