This started a couple of weeks ago, and since it's my work computer, I have no idea if something got pushed onto my computer that messed up excel, but this is really irritating.

Basically, the main part of my job is that I get excel files from clients, then I have to take specific info from that file and work with it. So I copy/paste it into a new excel file. Recently, I started getting this error message when I tried to save the new file:
"Y:\GEO\Test.xls cannot be accessed. The file may be read-only, or you may be trying to access a read-only location. Or, the server the document is stored on may not be responding."

None of those things are true, as I can save any other kind of file in this location, and I can actually save the original excel file(from the client) in this location. As a matter of fact, the only work around I've found is to actually save OVER the original document with just the data I need. But I can't change the name when I save. I have to do that later, in the file list. It's a very tedious way to work, so I was hoping someone might have an idea what's causing this or how to fix it?!
