After Install = Whitescreen

Hello Supportteam! 🙂

I need 2 annoy u again.. sry for that!

We moved to another Webhoster, so we wanted to set up our Page again on a new Webspace.
I installed WordPress, I uploaded Blackfyre, I activated Blackfyre and than I got a Whitescreen – Cant access to my Page anymore.

Can u maybe set it all up and activate the demo for me?
We need it as soon as possible, and WP hates me and dont wanna work for me 😀

Greetings
