Replay Media Catcher 4 does not remember registration code

[Paul J.K.]

Every time I run RMC 4, it tells me that I need to enter my registration code.
After I do that, it says "All product restrictions have now been removed".

The next time I run it, I have to do the same thing again.
Any ideas on why it's not remembering my license code?

Thanks in advance for any replies.

[Edit]Well I'm not sure why, but the program has now stopped asking for my registration code each time I run it.
The last 2 starts have been fine, so I'll have to see what happens in the future.
I did verify that my registration code is listed in the Registry, at
HKEY_CURRENT_USER\Software\Replay Media Catcher 4
