Problems activating?

Everytime that I attempt to log into my Stardock account to activate my Start8 on this computer, it doesn't seem to cooperate. I need help, as... without Start8, this computer is useless to me, I depend on the program a lot.

I've attempted to reinstall, ect. Even used the trial for a bit because of the lack of options, but is there anything someone can do to help? Every time I put in my password and account, it just takes me back to the screen asking for the password or if I want to use the free trial... which is blacked out, obviously.
