I Have several accounts of severs running the 1.0 account and i recently updated to the 1.63 patch only to realise that I now can't access any of my favourite servers and I will have to start afresh in another server. I know I could reinstall the game and just leave off the patch but ive been getting BSOD and other weird errors (including the game minimizing like i hit alt-tab when i didn't and the game will then not maximize out again untill i close it and start the game again) and im hoping that maybe this patch will help reduce/ eliminate them.

Can I connect to a 1.0 server when im running the 1.63 patch, if so, how?
Thanks for any help in advance.
