Couldn't find anyone in this topic that has the same problem as me..

I can't even start up Alarmed. I downloaded the program from the repos and installed it without any errors. However if i try to start up the application, i get a black screen with the loading sign at the top (same as refreshing mail). And after a few seconds it closes the application. I tried rebooting, that didn't work.

anybody have an idea?
Thanks
