This worked fine for me, but I think I found a way to get you past it. (assuming you just aren't forgetting to use the abbidon contact..but if you got this far I doubt it!)

Load the save game with the problem, then type

`TRIGGEREVENT Event Abbidon Operations 6 Start C`

EXACTLY like that, including the ` on each end.
Its a bit of a mouthful, but what this does in enable the next mission manually. You may have the leave out the Event before Abbidon, I'm not sure. Capitilzation doesn't count matter.
