As suggested, I tried activating the GOTY edition on Steam using the GameSpy key supplied by Amazon but it did not work (either did the primary serial key).

So I applied the patch again and tried using the GameSpy key instead of the serial key when prompted for activation key but it did not work. So I had to uninstall and reinstall again.

Thanks for the suggestion though - now it is just wait and see what tech support says on this forum.
