That's how. I even have the Wizworx CD from which I uploaded the game from and it gives me the same message that it can't find Disk 3 on drive D:... and yes, I remember I got it to work somehow back in the day. I get the error after I select race, gender and class.

I think I finally got it. Reuploaded, redownload and try. This time use POOL.bat to start the game. (As long as you use the same mounts, you may use START.exe directly instead the following times.)

It works! Thanks a bunch mate! :D

Others that have this issue should also check the .cfg file settings in the game's root directory to ensure the save folder is in the same location the program looks.
