The checksum is also in the rome/logs/setup.log file, search for the string "checksum".
But deleting the map cache should definitely not cause the game any problem at all. OK, let's try this: delete the contents of your beta copy folder and copy the working Steam folders across again. Manually delete that new map/cache folder, plus the settings.txt that came across. Run up the Steam app if it isn't running already. Now manually run romegame.exe from that location and confirm it loads OK, it should write out a new settings.txt and a new /map/cache/ folder. Exit the game and run it up again, it should get IYID now.
If so, expand the beta patch again over that installation. There's no map/cache in the beta, so delete that folder again and run up the game.
Andrew,
I had the same problem as mcpenguin and my checksum was exactly the same as his: IUJY.
I followed your instructions exactly. My Steam checkum is version 2.32c IYID. I deleted the copy. I copied the working Steam folder to c:\Games. I manually deleted the new map/cache folder and the settings.txt. The Steam app was already running. I manually ran romegame.exe and it loaded ok. It rebuilt the map/cache folder and settings txt. The music starts. I exit the game and crash with a windows message saying Rome has stopped working.
The crash happened no matter what action I took after the game has loaded. It did not matter if I tried single-player, multi-player, tutorials, credits, or exit. Whatever I chose the game crashed with a windows message saying Rome has stopped working.
The only way for me to run the game from the copy location was if I DID NOT delete the map/cache and/or settings.txt.
So I deleted the copy again. And recopied the Steam folder across as before. I did not delete map\cache or settings.txt. Running the game manually from Romegame.exe works ok. Checksum is IYID. Everything is fine. I applied the patch to that. The game loads, it runs, and everything else but it has the checksum IUJY.
Finally, I deleted the copy again. Verified the Steam cache (there were missing items) and kept verifying the game cache (there were more missing items) until it said the game was ok. Then copied it to the copy location. Applied the patch to that. And now I have the checksum XEVC.
Phew....
I verified the game files after I originally downloaded the game from Steam. However, in my Steam Library I have two entries for the game. Europa Universalis: Rome - Gold Edition and Europa Univesalis: Rome - Vae Victus. I remember verifying them both and I am wondering if that caused the problem since I verified the the Gold Edition first. When I finally got it working I only verified the Gold Edition.
Best wishes,
Steve
