first of all, the reason i started this game in the first place was to play with some co-workers. so far the game is good, but:

general, and party chat do not work at all for me (but tells work just fine)

and the biggest one, a cant add anyone to my friend list (which is the reason i started playing in the first place) whenever i try to add someone, i get "error code 122". i read online that "122" has something to do with a visual card, but i dont get why a visual card would impact adding a friend.

my game also freezes for about a minute when i open my character sheet/inventory/or anything really..

thanks for reading/helping.
p.s. im using windows vista.
