PLEASE help me. I'm getting a bit tired of Lion, after my upgrade from snow leopard.

It's about saving changes in different old documents.
I'm using iWork, office and Curio for different projects, but when I try to save my changes/additions I'll get this message in Curio: "File error - Cannot save changes. Is the file read-only?" and this one in pages: "Document "xxx" could not be saved automatically. You don't have permission".

When I right-click and look at my permissions it says both read & write.

All my documents were created under snow leopard before the lion upgrade.
Please help this danish student...
