PROBLEMS WITH RPG MAKER 2003

I just got the RPG maker 2003 to play a few games, I managed to start one game, Schuld, and got to I guess the second part of it where he chases Rachel (I guess) and now none of the directional keys (arrow keys, wasd, number pad) are working. The only thing that is working is the x and spacebar keys. I can't move anywhere, just open the inventory. I don't think I pushed any buttons that would have caused this.
I've tried exiting out of the game itself and then the rpg maker and retrying, but it won't work. I've also tried different games for rpg maker 2003 and they all have the same problem.
Can Someone help, please?

I think I figured it out, other than the fact that her name was Maria and I was completely off the mark, I had plugged in my zune and that's when it messed it up. I disconnected it and then restarted my computer and now it works fine. I guess I just shouldn't use anything in the usb ports while playing because it thinks it is like a game pad or something.

Thanks though, Cherry. I'll keep that around encase it something else happens. :)
