(Spoiler) Mission 4 problem (Operation Arrowhead)

[Hailfiretank 1]

First post, so here goes:

Basically, I've been playing the Arma2: Operation Arrowhead campaign, and I'm now on mission 4: Coltan Blues

I've made my way to the part where the Takistani man gives you the bomb defusal code. I know that you are meant to click on the 'enter defusal code' or something, and it brings up the menu with takistani characters. I've entered the code multiple times (the code doesn't change), however the LED at the top doesn't turn green, and the bombs keep ticking.

Any ideas?

And apologies if this is in the wrong place, it's my first post on the forums

Thanks

Not to worry, sorted it :P
