Problems after installing US versio over EU one

[BlackSmith81]

Yes, it was stupid thing to do, but i had high hopes that there would be so many similarities that there would be less dowloading so i would get faster ingame.
Everything went fine until i was supposed to get to the intro part as then i got slapped with error that some files was wrong or something. 'Oh well, back to plan A' i thought but after game was once installed, i could not anymore change the downloaders install path.
So i tried to uninstall US version. That resulted to completely empty DDO folder. So that didn't go too well. Instead of having both versions i ended up with none.

I was hoping that i now only need to download the small client and it will upgrade slowly, but instead now the dndclient will simply launch up, do nothing and shutdown itself. No messages. I tried to clear registery from any traces of DDO, but didn't help.

Now i am trying to install the game by downloading the ddostandard.
Any ideas will it help or do i need to go dig more in registery with other keywords than turbine?
