Hello everyone,
Thank you all for your replies.
And yes, Dennis is right. App. Options -> File -> Default CC files should be network shared location (the same for all networked users), because every part used from Vault is copied on that location. Now I'm asking myself what is the purpose of the Vault then… but, the thing was that everything worked just fine before we upgraded our systems to Windows 7, and now I’m guessing that our local App. Data files were on some Public folder, so we had no such problems. And it was so strange to me that it didn’t work now.
Anyway, now we all know the catch. 🙂
