Action Replay problems

[Notsoocool2003]

I have a modded ps2 with a magic 4, now my problem is loading backups with codes, it goes to a "updating codes list Please wait" and freezes, if i use the orginal it works fine, any ideas, comments on what i might be doing wrong? Problem game ive tested was Devil May Cry 2.

Thanks agian guys
