please help
 

Hello,

I'm running through the single player mod in star wars empire at war... i've become stuck on level 8 I believe, the one called needle in a hay stack.
I played the level once and han's ship was disabled, I played it again and the same thing happend. then I had to wait for him to return after he was disabled, which he did.

But now for some reason, I can't send him back to the astroid field to handel this mission. I drag him over it and it doesn't do anything.
also when i'm in a battle I can't call for any reinforcements.

please help!
