browsershots.org

Not sure if I should even bother posting this BUT, as a Mac designer, I always use http://www.browsershots.org to see how my design is coming up on the PC in various browsers. Been doing this for sometime. Suddenly today or within the past few days of me working I installed something (i think) that blocks this.

If you punch this url below into http://www.browsershots.org I get an robot error. http://www.supportmyhabit.com/advertising/

Any thoughts or advice as always would be greatly appreciated.
