Restored wrong info to my h4350 IPAQ

I accidentally used the wrong memory card to restore data to my h4350 and now
my PDA won't work. I used back up data from my rx3000 and now the h4350
turns on but won't connect to my PC and won't allow me to do anything or open
any files. Any suggestions for restoring back to the original system? I
sent a message to HP active support and haven't gotten a response.

Thanks for any help or suggestions.
