Just updated again, and still no split screen but thanks heaps for the link. I will give it ago.

OK thanks for that.

I just bought this game on steam because I wasn't happy with the split screen in TM turbo. Now I find there is no split screen at all, but apparently there used to be - see here:

So what happened?

Not happy.
