Enter key isn't working on Keystation 32 Mini

I just recieved my M-Audio Keystation 32 mini which I bought to learn some basic piano/keyboard things and just fool around with in Garageband. I have been playing on it for a couple of hours now and noticed quite early that the Enter/G4 key didn't work as a normal key for playing. At first I didn't give it much thought as I for some odd reason just figured it might not be for playing since it's the enter key. But when I tried changing the velocity curve for some drum recording I was unable to click enter to confirm my choice. I have only had the keyboard for a couple of hours and it's been like this all the time, so I am either doing something wrong/using wrong program etc. or the keyboard is having some malfunction. Has anyone else experienced something like this, and if so know how to fix it? As I already had some problems ordering the keyboard which involved a couple of emails back and forth I just hope I can avoid doing that again if possible.

I am using the keyboard on a MacbookPro running 10.8.2 and the latest version of GarageBand. I have not downloaded any drivers as of yet, since I was unable to find any recent ones.

Any help would be much appreciated!


Cheers
