It's their problem. Not only that, you didn't share the name, their URL (link) so not much can be said except it's a bug or old software that is no more.

I've a software program that requires online registration in order to get the password for full activation. The registration date had expired and I tried to reinstall several time but it keeps prompting that the trial period is over. May I know how to clean install the program again to validate the registration process. I'm using Win XP - SP2.
