So I was fooling around in the Glue images, and Lua and XML files in my client, but once I packed them into MPQs and started wow, it said that my files were corrupt(big surprise.. I'm the one who changed them). So I did some searching around and someone mentioned that wow matches those particular files to a digital signature file, and that said file was encrypted.. rather strongly.
So, does someone have a way around this? Will +Rep anyone who lends a helping hand and give them an imaginary cookie.
