eM Client goes straight to contacts page when starting

A client who uses eM Client software has messed it up. When the program starts it goes straight into the contacts page. I believe it should go straight into the email page. How can I change it so that it loads the email page when starting? Spent more than 2 hours trying to figure this out with no luck. Can someone point me in the right direction?

Menu > Settings > General > “Show on Startup”. Select where you want it to start.
