Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi,

as I logged in a few minutes ago I noticed that I could not move farther than a few meters from the point I spawned at (in front of IF bank) and the world wasn't even loaded beyond that point. I sadly forgot to make a screenshot.
I disabled all addons, deleted the cache / WDB and even configs / WTF but it didn't help.
Then I had the idea to use my hearthstone and see if that works.. It didn't. I now have the exact same problem in SW.

See for yourself:

After jumping at one of the invisible walls I'm now stuck floating in the air. http://i.imgur.com/Cn048KQ.jpg
Come and laugh at me!

(No, seriously, please fix this and help me )

A GM teleported me around which was fun but sadly didn't help at all. I'm now stuck at the Goldshire Inn.

Your client files might be broken or corrupted. Did you install using the official Nostalrius client? Have you tried a full uninstall/reinstall of WoW?

Greetings!

Issue has been resolved. No reason to keep discussing.

Sincerely,
Ithlien

Want to note here that reinstalling is what fixed the issue, in case someone has the same problem! Thanks again for your time Ithlien.
