Cant export files, need help quickly

Hey guys, I got an error when exporting wav. files…it says that the disc is full, which is really strange because the disc is not really full.

Ive tried with different audio tracks, I click “export” and this error shows up which says:

error when saving as WAV (microsoft)
file (disc full?). Libsndfile says “”

Anyone who knows what to do?

That can happen when you use punctuation marks in your filenames. Upper and lower case letters, numbers, underscore and dash are the only unconditionally safe characters in filenames. Never use dates. Today is not 6/23/12, it’s 20120623.
