Cannot access the Gold Standard MCAT Prep Member page now!

Hi,

I paid for the CBT tests this January and should have access to the site for a year but I cannot get into any of their pages now.
Suprisingly, I was in the site this morning and afternoon - but seem to be getting a Page Not Found error now. Is the site down for some reason ? Has anyone else faced this? I have tried all these urls and none seem to work.
