I have a problem with loading files to EFI colorproof XF. When I add a new file (no matter how big the file is), I see a command "0 jobs of 1 already uploaded". It takes a long time, when the command disappears, but the file is not added.
have you already tried a server-restart? If that doesn't fix the issue try to resatrt the whole machine. I solved similar problems by restarting the f****** windows.
