Firstly, make sure you enter your registration details exactly as they are!
Both the registration key and registration name are case sensitive. It's better to copy and paste your registration details instead of typing them manually.Then, check, if you're using the same PC account you used when registering your IC. So, try everything again, and if this doesn't help, please apply to Bolide through the site form http://www.bolidesoft.com/feedback.html
, specifying your problem, order number and e-mail address given at registration. Good luck!
