User Cant upload Files?

[SIbuna]

OK so i run a site running coppermine 1.3.x IIRC its 1.3.3, anyway a user that is a friend of mine has an account on it and up until yesterday he could upload stuff fine, because he is a friend i give him unlimited space for files, he is currently using about 200megs of space with 195 files uploaded, last night while he was uploading files all of a sudden it tells him that none of his files were uploaded successfully, same thing happens today, i have had him restart his comp and clear out his cache and cookies and nothing works, he has tried it in both IE and Opera, I can log in as him from my computer and upload just fine to his account

so im guessing its something on his end, tho i have no idea what, and was wondering if anyone here has ever experienced anything similar to this, and if you know how to fix it
