Can't log into WoW, can I fix this?

[Chainer]

I think I've downloaded the US trial version but need the EU trial version, is there something I can do apart from download again? [Please don't make me download again.... :cry: ]

Edit: Had a search of the forums, found my Repair.exe file but it said it couldn't connect to the server.

For those who are wondering I managed to fix the problem, all you need is a european WoW.exe and to change your realmlist.wtf
