Ah! ...and oh.It's not managed to decompress the main package yet, so that'd be why the file I suggested wasn't there.Try uninstalling from add/remove programs, manually delete the folder if it stays, and then re-install it into a folder with no apostrophe (so c:\MHD\ or the like). That's rather clutching at straws, I admit. It shouldn't be crashing out like that.Is it XP sp2 or sp3?If you have HeroStats or the Titan Network Tracker, do they run without crashing?Are you logged in as an administrator?
