@ rty. If you contact krazik you can help solving the problem. Not only for yourself but for others too.

As krazik said:

Quote - If someone else w/ the Login issue has the time to help me resolve it please IM me and I'll send you my contact info. We can't reproduce it here and need your help. It won't take very long and I'll make it worth your while.

Going through the login and checkout step by step together (you from your computer and krazik at CP end) will help solve these problems once and for all.

Lets all do what we can to get this solved for the good of all. :o)
