I think I may have found the problem. For some reason firefox is not working with the online store, but Microsoft explorer is. I can still use Firefox for the forums and the other areas.
I am running the latest version since firefox automatically updates itself. I have been trying to figure this out since it appears to hang at the login screen after the login info is entered.
I have always logged in from the website which is saved. I did try from @mytrainz and it did work. The test for you is try browsing for the website and check to see if you can log in.
