I can′t to log in (wp/admin) with Lupercalia

Hi! Sorry the question. I choose Lupercalia and i created my page, but when i log out and try to log in again nothing appears, just a white page. My service support told me that was a problem of Lupercalia Theme. Anyone does know what i have to do? I really want to use this theme.
Now i can log in because my service support took off Lupercalia theme.
(And sorry my english, i am not good speaking it!)
Thanks!
