'Invalid CD key' error after installing the patch.

Sometimes a conflict in the updated files can prevent the game from properly identifying your CD-key. Usually, refreshing your CD-key will resolve the issue. Note that this will only correct the error if you used the same Windows account to install, patch, and troubleshoot the game. If you have switched Windows accounts at any point it is recommended you uninstall, reinstall, and repatch using the same Windows login.
