Diablo 2 Crashes as I join games since screen res change

I just installed the game last night had it working fine. Today I went into settings while in game and just clicked on the video resolution 800x600 I think was defaulted, as soon as i did i crashed and now i can’t log into a game just an instant crash.

I uninstalled the game three times and it sill does the same thing.

that means that your resolution was saved. i am however unable to find where. you should be able to reduce it by running it in software mode.
