Problem with removing and reinstalling "Spirit" Theme

Hi all you great people..

I installed the Spirit theme with Upfront,- really a great tool when you get to know it i think.. Much more intuitive..

But i got a problem,- i toyed around with Spirit and all of a sudden i had nothing but a white area. Can do nothing, not even reinstall to the default looks.. Can you help.. http://www.prosim.nu
