Entering notes with MIDI-keyboard

Hi!

I´m using a keyboard (yamaha psr-e333) to enter notes in Musescore via an USB-cable. This works fine in Musescore 1.0 but in Musescore 2.0 there is a problem. When I start Musescore i can hear the keyboard when I play it, but as soon as i go in note entry mode by pressing "N" I cant hear the keyboard and nothing happends when i play it. If I manually insert a note with the mouse I can "record" other notes on that same beat with the keyboard. So, if I manually insert the C quarter note with the mouse, and then I press the note D on my keyboard C and D will sound at the same time as quarter notes, Musescore wont move to the next beat as in 1.0.

Anyone knows what I´m doing wrong?
