Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, I tried looking up solution for my problem for quite some time. I have two identical laptops in one household, only one has win7 and one win8. Win7 laptop is working fine with nostalrius. I have copied my wow file, transfered it via flash disk to win8 laptop and could not login (stuck on logging in, doesnt move from there, no disconnect, just stuck on logging in, forever).

I have tried deleting WTF, WDB, changing realmlist, pinging the ips, running as administrator, everything seem to be ok, except I can login on win7 laptop and win8 laptop freezes wow on logging in. I cannot even cancel the logging in window, since it crashes wow. Any suggestions?

Sounds like possible firewall or antivirus interference. Have you tried temporarily disabling all security programs to see if it behaves any better or logs in successfully?
