no description, just "Error uploading".

Normally the failure was due to oversize. In this case, please open the dvdfab_internal.log file with notepad, scroll down it, cut and leave the last few attempts of the log file and then attach it here again.
Every log entry should start with something like DVDFab 11.0.0.3 (2018/11/18 11:33:44) (X64).
If still have the same "Error uploading", try to send it to us via PM, attach a screenshot of what you get.
