I have a Big Business game that I've hosted for a few years now. I have also for a long time had a problem with the history file. I have banged multiple times BUT still have OLD history in the game...it only shows 1 or 2 days of current history, then everything else in history is OLD history....like 2 or 3 years ago???? I cleaned the TWGame.log file even deleted it. and still there. Apparently I am not looking at the right file.. Any ideas???
Thanks,

Actually after some investigation I find that MOST of my games were this way. I ended up deleting all the game folders and importing new copies of the TWA files.....then banging the games again, which did fix my problems.

In newer versions of windows, UAC relocates data files in restricted locations (i.e. the "Program Files" folder). I'm wondering if this is what happened to you.
