Pleco software help

Have any of the other Pleco software users (AuntySue, Yyves?)  had a problem with their Palm computer crashing.

Mine did it yesterday. After I rebooted it won't recognize the unlocking key for my software. And there's no sign of my flashcards. I have most of them backed up on my computer, but I'm not sure how I restore them.

Life without my electronic dictionary is a scary prospect :-(
