Action Replay DSi Problems - Can Someone Help Me?

About a week ago I added a code to my DSi Action Replay for Pokemon Diamond that was supposed to let me catch Pokemon that Trainers were using and I added the code manually. Well my DSi doesn't work not and I am thinking that the code bricked my DSi Action Replay in some way. When I turn my DSi on it recognizes the Action Replay but when I start to load the Action Replay it gets stuck on a white screen. I have already tried holding the A+B buttons and then START+SELECT and that didn't work for me. If you have any ideas please let me know as I would like to get my Action Replay working again soon.

I got the same error once. Grab your cable, connect it to the computer and run the software. Go to the little Action Replay icon in the very upper left corner (to the left of the text "Action Replay DSi Code Manager") and click. Choose the last option, "About Action Replay DSi Code Manager". In that box, click reset hardware. Let it do its thing, and you're done. Good luck!
