Upgrade problem - site disappeared after replacing /ndxzstudio

Replaced 'ndxz-studio' with 'ndxzstudio' (old for new)

I deleted the old folder 'ndxz-studio' before checking the back end....

I have now replaced 'ndxz-studio' again, so both of the folders are there...

when i type my address, for both back end addresses this happens:

max-dade.net/… = nothing. a white screen
max-dade.net/… = database is not installed

What do I do?
Do I have to start again from scratch?
