Can't start application manager

Can't start application manager

I have installed ApplicationManager at Ubuntu 12.04

after starting I see following errors
in StartUpLogs_err2:
MySql daemon is not running on your linux machine/ PLease start daemon and retry.

in StartUpLogs_out2:
usermod: user postgres is currently logged in
waiting for connection in the database for Postgresql

as well, I have made two installation,
on same machine with different folders, and  not deleting first of them.
Same error happens for both installations.











what can be reason of error, and how to resolve ?
thanks
