Atomic Systems

I have downloaded and installed the GWR Steam Railmotor, but cannot get the Career scenarios - apart from the first one (the power bogie only) - to run. When I select a scenario, the computer goes on to the sales page, and the sim stops at that point; effectively, it doesn't even start. I can get the unit running in the Quick Drive mode, but that's all.
Could anyone help me with this please? I really would like to be able to play the scenarios, so any ideas would be most gratefully received.
Many thanks.
Stuart.

Sounds like it downloaded incorrectly. Probably best to clear cache again and see if that solves it, and if not, then do a full cache verify to make sure it got everything.

Thanks Stuart - I'll try that.
