Cannot determine modules type - Flex

Hi,

I have a sudden and urgent Problem. I am using: idea-IU-95.627 (on Ubuntu).
All Flex related stuff dissapeared from  IDEA.
I haven't changed anything, except closing and restarting IDEA.
All my Flex projects open with an error: Cannot determine module type ...
Also, if I try to create  a project/module, there is no option for Flex facet.

Tried reinstall an older version idea-IU-95.607, it behaves the same.

What should I do?

Thanks
