I finished my Java-programm for switching between ProMod and Retail mode.
So here's a short tutorial how to use it (it's in the README file, too):
Installation:
1. After installing the Mod, open the shortcut "TXProMod.jar" on your desktop.
2. Click on Backup and wait until it has finished (you will get a message). You only need to do this once!
3. Now you can switch between TX ProMod and Retail mode
Have fun! There's much work in it ;)

Ok, that's it! Enjoy the new gaming-experience!
