You can't solve that. I think you twisted one of the corners by accident.

:?:
or you could just do [UF UR UL UB UR UL]x2 :roll:


(U=red, F=blue, L=yellow which I'm assuming makes R=orange and B=green right? Mefferts Helicopter scheme which is traditional scheme with white and orange swapped)

Peace,

Yes, you can solve that. If it's two corners swapped it's a possible scenario.
I solve this parity, if you can call it one, by turning 3 adjacent edges around their corner, always one after another in any direction. After 9 turns (twisting every of the 3 edges 3 times) you end up having 4 corners swapped. Move would be: [UR FR UF]x3 If you then just use your alg for swapping 3 corners you can solve it. Assuming you have an alg to swap 3 corners, which I think is the case since you almost entirely solved the puzzle except this "parity" case.
Now my method isn't really elegant or fast but it's easy to memorize. :) If you want to speed solve, forget it, otherwise it does work.
