Dear Players,
Since I couldn't find any thread ( which wouldnt include downloading retail data rofl ) nor explanation upon the topic, I figured it out on my own. If you are facing problem with language, when you occur "Cannot Stream..." reffering to Data/enUS all you have to do is:
1. delete >WoW/Data/ruRU (since you wont need it)
2. delete WoW/Cache
3. delete WoW/Data/Cache
4. delete WoW/WoW.mfil, WoW.pfil, WoW.tfil
4. open with-select program Notebook- WoW/WTF/Config and change in 2 1st lines ruRU to enUS or enGB (I bet every1 knows this step because its the main issue :P)
5. run launcher PandaWoW-32/64
Obviously if you want to play on english launcher you will have to download the translation. The only way to download the translation is to remove russian translation and saved files to it which is ad.4
It's gonna take 1.2gb to download -neccessary- and process will be going ingame. No need to worry those are only translations so even if you have 100kb/s it wont hurt your ping. Game is ready to go instantly
Best Regards Guys!
