Migration errors "Behavior aspect is absent"


I'm not able to reopen a project I have done in june 2016. I don't remenber which version of MPS I was using at this time.

And now when I try to open with MPS version 3.0, 3.1, 3.2, 3.3 and 3.4 I have an error " behavior aspect is absent" for all languages that composed this projet and all languages are empty in MPS but not in file system. 

The migration tool don't allow me to fix this error.


Could someone tell me how to fix this ?


Best regards

I suggest you took the original project (the current one has probably been corrupt already) and try MPS 3.3, which was the current version at the time. A migration might pop-up, if the project had actually been created by MPS 3.2.
