If I am getting this right, the problem you are having is it giving you a error after you already typed in the name.
The reason it gives you this error is because you didn't give the drive enough time to read the disk. You probably put in game and hit install, then right away hit ok and began typing the name of the game. You have to first put in the game select install, and wait a couple of seconds. The drive is spinning and reading the disk, then after a couple of seconds tyou can hit ok and begin typing the name of the game. You wont have this problem anymore. The reason is once you hit OK, the disc stops spinning. If it didn't read enough of the game prior to you hittinh OK and typing the name, then it will give you an error. Hope this helps
