Kadaan.

I went to C:\Program Files

I copied the World of Warcraft folder. (The whole thing)

I then pasted it directly into C:\

Then I renamed the folder to WoW1 ( did this all the way up to WoW5)

Now, go into one of the 5 folders. Make a shortcut of the wow.exe and rename it WoW1 all the way up to 5.

If that doesn't work. Let me know
