It solved my problem!
If you have onboard sound card (at least that was my case) go to Settings\Audio, disable EAX, select Software acceleration, Medium Quality and you're ready to play without the infamus “there is a problem with your connection”.
Note: When installed patch 1.2 EAX settings went back to default (ON)!!!

Og fyrir þá sem skildu þetta ekki þá ferðu bara í leikin, ferð í options -> audio og slekkur á EAX
Vona að þetta hafi hjálpað einhverjum =D
