Error Message - Need HELP ASAP

[PMG]

I'm trying to publish to my earthlink server, and I keep getting hung up
with the following error message:

Server error: Cannot close file ".2004 - 04 011.jpg.tmp".

I click ok and then it stops.

There's no error number. This is happening a lot lately. I fixed it once
before, but I can't remember how. Is this something I can fix within FP or
is it something I need to go to my host provider to fix????

Thanks
