Nostalrius Begins - Quality wow vanilla realm (1.12)

so i was going to connect to the nostalrius server and i clicked on the test realm by mistake. Becouse i dident have access to this server i was automatically logged out. So on the log in screen it says that i am connected to the test realm in the corner to the right, so if i log on i get thrown out. I tried reinstalling the game, but it did not work. so what should i do?

Best Regards,

Delete WTF and WDB Folders and then it works

I cant find WBD file and still have the realm help?

I have this problem and i cant find wdb files

WTF and DB folders exists within where you installed World of Warcraft Classic to.

If you're unsure of where you installed it to, find the shortcut you double-click to open WoW with, right click, and select "Open File Location." This will open the folder of where WoW is installed on your computer. In there should be folders labeled "WTF" and "WDB." Delete them.

Alternatively, you can also follow the instructions in the sticky thread for "Disconnected from server" error.
