Domoticz

Hi!
Next scenario:
I am having domoticz up and running in a scouting building. Than a crash happened. Impossible to boot the pi.
At home I reinstalled another SD card with only using domoticz. I copied an older database and tried to start Domoticz but it fails to start.
What can I do? Originally I used a number of hardware devices which are not available at home. Might lack of these holds domoticz to start?

TIA

update:
I did a database restore via settingsmenu Than after a while the original dashboard popped up for a few seconds. Than the message that no devices where yet there. The solution was to restart the pi and logged into Domoticz with original credentials.
So problem seems to be solved.
