Website not working - CubeCart

[nohart]

Hello yesterday I installed CubeCart v3 and worked on it for about 6 hrs. Everything was working fine. Then today I am being restricted. That is that every time I log in to my shopping cart control panel if I try to access any part of it I keep getting prompted for my log in and then it just keeps looping in circles. Also when I try to pull up my web site now it just times out. http://www.aclassactapparel.com/

Edit:

ok my site comes up if I use http://aclassactapparel.com but not http://www.aclassactapparel.com/ I don't know whats wrong. Everything was working fine yesterday...

Edit:

I cant log in to my conrol panel either? http://starka.x10hosting.com:2082/
