Locked pcm?

I just got a cable, adapter, and dl'ed freescan , datamaster, and pccomm.exe

None of them work! In datamaster, I used the test cable function, and it said my converter was fine, but my pcm was unreadable. What would cause this? I have heard of some pcm's being "locked." How can I tell if this applies to me?

ps. I used hyperterminal and the converter works. I am using the Belkin F5U103 converter.
