Cataclysm Unable to connect to Cataclysm

[Pimpsqueak]

Self-explanatory title. I just installed the Cata client but I am not able to connect. Thought something might be wrong with the credentials, but even after I changed passwords it still wouldn't connect. Was supposed to play this with a friend of mine and it works fine for him, but obviously not for me.
Any fix for this issue?
Thanks.

*Update*
Tried to exit out the application to retry, but apperantly I
"Cannot stream required archive data. Please check the network connection"

I figured something might be wrong with WoW.exe itself.
I tried to run WoW.exe as an administrator where I get the notification that my system cannot find "WoW.exe"
(Which I find odd considering I am looking at the file right now)

And then Bittorrent gave me a warning saying that my torrent has failed (after I've already downloaded it fully) due to my file being missing. What the ****?

Any help?
