If you're having trouble unlocking your software there are three likely causes:
1) Typos. Make sure to cut and paste your name and serial number to avoid typos such as confusing 'O's with '0's
2) Firewall. You may need to temporarily disable your Firewall in order for AutoRun to validate.
3) Free Updates Expired. Your year of free updates might have passed. You can still use your current version of AutoRun as long as you like, but if you want to use the latest version you'll need to purchase an upgrade: http://www.autoruntyphoon.com/upgrade.htm
