After hours of messing about with various utilities and RegEdit I thought I'd fixed it. I hadn't. My Enigma experience is currently ruined - CTDs all the time, I cannot even start a patrol. I hasten to add this is due to no fault of TAG, this is entirely due to the incompetent imbeciles at Nvidia who can't write software worth a damn.
Well, I feel marginally better for getting that off my chest. Now to try to restore my system to a working state...
[Edit] FYI, my card is an Abit Siluro Ti4200 128MB RAM. Abit used (I'm fairly sure) to reccommend the Nvidia drivers, but I note they have a recent version of their own drivers on their site now. Maybe they've got sick of support problems from poor suckers who've installed Nvidia's viralware. We shall see if this returns my Enigma back to its happy working state. Oh, and if I ever get sunk from this day forward, or even one of my torpedos fails to sink its victim: It's Nvidia's fault! [/Edit]
[Edit 2] That didn't fix it either. Basically, Nvidia has totally fcuked up my system for playing Enigma. I'm really quite upset by this. What had I ever done to offend them? Their mothers were hamsters and their fathers smelled of elderberries, I'll wager. [/Edit 2]
