A couple of days ago a GoBetwino user ran into some problems with using GoBetwino with a Leonardo board.
Since i don't own a Leonardo board, PaulS was kind enough to help me with investigating the issue, and we found that there are some breaking changes in the way the serial communication works with Leonardo. You must have DTR enabled, this was never needed for the other boards.
I have made an updated version of GoBetwino that fixes this issue and a bug the prevented the "check email" function from working under certain conditions.

Thanks to PaulS for helping with the bughunt and testing the updated version
