Not an expert , but try this...
First, you probably don't want "config.wtf" on the first level in your WTF. Sets the localization (language) to DE, and other in-game settings that don't really have anything to do with the UI. I do not think the author was supposed to include that file.
Same with the WTF files on the next level. Usually all you need are the files in "WTF\Account\ACCNAME\SavedVariables".
Then I'd try loading it without Reflux, to see if you get any error... Then read Reflux's page:
http://www.wowinterface.com/download...11-Reflux.html
See if Reflux is something you want to learn how to work with. Since that's specifically about profiles it's the first thing I'd check.
If those two things don't help, try loading it without Prat. I recently had some issues with Prat profiles.
Also these WTF files aren't "scrubbed" of profile settings specific to his characters on different servers, but I don't really think that will cause any issues. However, you can go through each WTF file and delete sections like:
Code:
["Gallahead - Frostmourne"] = "Standart",
["Hemma - Nazjatar"] = "Hemma - Nazjatar",
["Babayaga - Frostmourne"] = "Babayaga - Frostmourne",
["Tann - Frostmourne"] = "Tann - Frostmourne",
["Gwaehir - Frostmourne"] = "Gwaehir - Frostmourne",
["Tannhäuser - Frostmourne"] = "Tannhäuser - Frostmourne",
["Reineke - Frostmourne"] = "Tann - Frostmourne",
["Longstride - Frostmourne"] = "Longstride - Frostmourne",
["Hemma - Frostmourne"] = "Hemma - Frostmourne",
["Hallagead - Frostmourne"] = "Bär",
["Happa - Frostmourne"] = "Happa - Frostmourne",
["Geraint - Frostmourne"] = "Geraint - Frostmourne",
["Jahnsen - Frostmourne"] = "Jahnsen - Frostmourne",
["Tannhaeuser - Rexxar"] = "Tannhaeuser - Rexxar",
