Using a Surface Pro but having no luck, I seem to have tried everything to no avail.
I have even contacted GOG a number of times but they haven't got back to me.
They also seem to have deleted any threads relating to crashes.
So was wondering if anyone had managed to get it to work?

Forgot to mention I am using Windows 8.1

Well I haven't had any opening crashes so far, but I'm using Win 7 64 bits... May be this game don't support Win 8.1 yet.

Every time you contact support, your ticket goes back to the bottom of the pile. So, don't send any more tickets and wait a bit for the reply. Just after the sales, there's a probably a lengthy backlog of customer tickets, but even so I've gotten replies in under a week.

The game works fine on 8.1, though I'm not sure about the rest of your lappy's specs. Make sure you have updated to the latest video drivers and have installed.
