Can't upload new sketches to arduino robot

Hey guys,

I can't upload new sketches to my arduino robot after the last one (which was the example "logo" on IDE 1.5).

Now both of the atmega32u4's are locked and can't program neither. Any help is appreciated.

If I can't solve this, by USB, do you think buying AVRISP would help? (I think I will connect it to the ICSP pins...)
