You can put your Action Replay into the DS, and as soon as you turn it on, when the screen loads up, press A and B and keep holding them. Then, when the Action Replay screen loads up, press start and select and wait a few seconds. This will reset everything. Then, use the cable that came with your Action Replay to hook it up to the computer, and load up your Action Replay Code Manager program. If it's not installed, use the disk that came with the Action Replay. When it's loaded up, click 'Update' and this will delete all the games on your Action Replay, then load them all up to it again. This will solve your problem, but any codes you entered for your games manually you will have to put in their again. Hope this helped.
