Saving documents in MS OFFICE ´07 with Windows 7 X64

Hi all, The problem in a nutshell is when I try opening or saving documents in MS OFFICE ´07 with Windows 7 X64 I always get the following errors 'C:' is currently unavailable. OR ::{031E4825- … }Documents.library-ms refers to a location that is unavailable.

I have inkling as to what may have caused it but have no tech knowledge: I installedan eSata drive and found a lot of the folders on my other drive being repeated on it. When I told my anti-virus to scan the esata drive it mirrored that on the other one.

The two drives seem to be linked so I deleted the files off the drive but then they didn´t even show up in the recycle bin. I unmounted the drive and went back to see the files again and everything was as it should be.

I launched MS Office but discovered that when I tried to save a document there was only the top and bottom parts of the box, meaning the white bit with all the data wasn´t there and click cancel then proceeded to close Office entirely!.

If you try to go to a different location using the box it just gives the same error message stated above? I would just like to know if anyone has any idea what is going on and how to solve it, thanks in advance. Dave
