Thanks Kival, but no; there is no entry in any of the users\app_data folders.

I did a clean rome 1.5 install, and EB is the only mod in that copy. I can force the game to create a new map, I can not stop the corrected_regions.tga from installing itself and overriding my tga.

I've spent 3 days uninstalling, reg checking and reinstalling with and without the trivial script. EB won't allow for the naval improvements I want to make.

SPQR will, so while I'll keep EB because it is very good, I'll see what I can do with SPQR or the Naval Mod for RTR.

Also yesterday I installed my Medieval/Kingdoms game, and there are some mods there I can use as a starting point.
