Continue. You are past V1 and with 3200' left you can probably get enough speed to get her off the ground. I'd run some of the electric stab trim to counter some of the nose down and try to grab 5-10 deg nose up and get her flying. Then again, in the CRJ, you should get a flaps fail caution msg if the flaps are out of the selected position, and a config flaps warning message and aural when the thrust is above 70% N1. It really shouldnt happen.
