Did you install the game from GOG? That's the only reference I can find for 18.104.22.168 as a version. If the game is crashing that early, it's possible GOG (or another mod?) made some edits to the EXE that are incompatible with the edits FTSE makes. (Since the edits go down to machine code level, FTSE is sensitive to any EXE changes beyond those explicitly used in testing.) Has anyone else tried FTSE with the GOG version of FT? I unfortunately only have the original 1.27 and Steam versions to test with. In the meantime, I can look to see if I can add further safety checks in the internal patches applied at program start, and report a cleaner error if the EXE is not compatible. Or, if I can somehow get a copy of the GOG version of BOS.EXE, I can maybe figure out a way to get the FTSE functionality to work with both.
