Program Freeze

I was playing as Portugal. A group of my Jinettes was attacked by Danish Feudal Knights. My Jinettes spent all their ammo, then bowled the knights over by charging. When my Jinettes were finishing the enemy off, I heard the captured enemy general sound... and my hud around the battle disappears... just goes black. All I can see is the main battle area... and it's frozen. The program froze. It looks like the last enemy captured was the general. The screenshot did work however and I have one of it...

Know any good server to put jpgs on to post here?
