Rest assured that's a widespread issue.
The Gamersgate website is experiencing a technical issue that's preventing users from accessing their entire store. Here's the error message that I received when I tried to view their website:
www.gamersgate.com - Connection failed
Error code 8
The proxy failed to connect to the web server, due to TCP connection rejection (TCP Reset).
