Beta Testing: never get to the beta

I log in, start to create a route, it asks if I want to try the beta and I do.

Then another window opens with MapMyRide in it.  I am no longer logged in.  I log in, chose create a route and the same window pops up asking me to try the beta.  I chose this and another window opens with me not logged in.  

When I try to create a map there, the pop up asks me to try the Beta and so on.

So, . . .?

 I am using the latest version of Firefox 2.

 I also hate it when I create a map in the regular program and go to save it and it tells me I have to be logged in before I can save a map and I was already logged in.  Then I have to do it again and sometimes have the same result.  Fix that in the beta also if it hasn't been done.
