Either this is you DT and you now have it fixed, or you are having the same problem that a guild m8 of mine had.The problem is a corrupted MIR installation on your PC.
The solution is to burn a CD on a friends PC (one where everything works) that contains the full folder structure and files from their C:\Program Files\WEMADE folder (or wherever the game is installed) and to overwrite your installation with this copy.
I'm @ssuming here that you have tried completely uninstalling your copy of MIR, deleting all remaining folders and remove all WEMADE keys from your registry, then reinstalling the full 1.2 client.
You spell Wizard with 1 z !
