So mods rejection method did not gave any results, so I made a back up of my save files and I'm going to reinstall everything clean and fresh.
BTW I was using MultiSh3 for multiple SH3 installs. one for stock and one for GWX. Had some problems when uninstalling
Then
After these errors I had to manually delete SH3 and GWX installation folders, rebooted pc, will clean registry and reinstall everything from scratch. Will do only one install with GWX this time. Will keep this thead posted if I dig something out.
