Subversion integration not working.

Hi,

I had some problem with a project so I closed it and created new one using exising sources (overwriting the project file) and now Subversion in the context menu is missing. Also the fact that a file has been changed (the blue file name) is not shown. The only avalible svn options are the Update and Commit in the menubar (the other options are disbled).

It was working fine before the reimport.

Is there any way to make it working again ?
I'm using II 9.0

The svn itself is working (I checked with TortoiseSVN).
