Nostalrius Begins - Quality wow vanilla realm (1.12)

Good morning,

yesterday I had trouble logging in, while I could play perfectly the last days.
I tried both login servers and nothing worked.

This morning I just randomly deleted the "Config" file and I was suddenly able to log on again.

Now, after 30 minutes of playing I got Kicked out again and it says " not able to connect".

Anyone out there with the same issue, who can help me with that?

Best regards,
Lyz

Deleting the whole WTF folder worked as a workaround..

Problem is up again.
