UPDATE from my last post (Couldn't edit, sorry)
SO I did what was suggested:
Went to E drive and deleted "/E/TDATA/0facfac0".
Went to Gamasave manager (in UX) and deleted saved game for DVD2Xbox (this also resets the old logo with the new one)
When I first launched the program, still the same error occured, but once I restarted the machine that is when all was fine. I suppose it didn't function the first time due to the old files still being in memory (should have been obvious, but at 2 am, not for me).
Thanks to those before who were able to pin-point what had to be done. Really appreciated.
