Uninstalled and reinstalled the whole thing under C:\GAMES\SEGA\Medieval II Total War.
Getting the generic shared text file error message.
Downloaded the file and unpacked it into the mods\ebii\data\ file. Twice.
Still getting the same error message and CTD on startup.
The instructions on the bug report thread say to open up build_scripts.ini and update it with my java location. How do I do this? Are there instructions somewhere? At least it was running before I reinstalled. Now it just CTDs every time I start it up.
