Patch 3. Hi Susan, this is actually quite a common issue.

Hearthstone-Packs und Co. Would get to loading sources then closed program. Any help is highly appreciated.

I would try an addon and sometimes it would let me choose a show, sometimes not. Jetzt Champion wählen und bis zu 3 Gadgetzan-Packs gewinnen This instability is part of why we recommend using official addons over third-party ones.
