Beta 8.0.692 won't start

Hi

right after installation the emclient starts without issue. after closing the emclient wont start anymore. it always says that it was not proper closed  and has to scan the database. after scanning the window closes but emclient did not start.

any suggestion how to getting emclient to work?
