To solve this problem run Microsoft Internet Explorer and from the Tools menu select Internet Options.
A dialog will appear, click the Advanced tab and scroll down to the Security section. Uncheck the “Check for publisher’s certificate revocation” option and click the OK button.
This problem only occurs when PCs are configured to have access to the Internet and then, in reality, don’t have access to the Internet. Predator applications are digitally signed just like every other program that is downloaded on the web. The digital signature is used to certify that Predator has not been infected with a virus etc.
NOTE: This problem can happen with any Predator application.
