How do you update all the different copies of WoW? I made a second copy to try out, but had problems on the last patch. I would start the second copy, get the out-of-date message, but when it quit and opened the downloader it said I already had the latest patch. I tried copying over the patch file and running it in the wow2 folder, but that didn't work either. Do I have to re-copy everything every patch?
