Back in the day I remember the hassle of trying to get this to work and it was worth the effort, reading reviews on steam recently and it seems that problem is still there (on steam) and comments were directing buyers to GOG......and quite right they were too. This game works perfectly, pop up says there's a problem but ignore that and your good to go. Its well worth buying again as its so cheap. £7.49 as i write this, and its one of the best games ever released.
