Nostalrius Begins - Quality wow vanilla realm (1.12)

So I went to make a new account using the directions in the config tutorial. I got the right version and server working for the launch but now my retail version won't work. On top of that none of the blizzard games work and I can't log into the client.

Can someone help?

Thanks!

As a first, make sure the nost WoW is in another separate folder then the retail one.
It can else very well be that they are working against each other.

I don't run multiple versions so i can not be of big help if this does not work.

I apologize. Was just a big coincidence that after I downloaded it the retail server went down for a few hours with no explanation. Everything seems fine.
