when I go into options it works , however it also goes blank when I click on 'load game' ...
Okay - Let's try deleting any save files you've got in the game's folder "saves". Perhaps it's something there that's causing it. Also, where have you unzipped the game to? Perhaps try and unzip it to desktop : )
it didn't work , the screen still goes blank ...
Hmm, do you have any other computers you could try running it on, to see if it has do with windows settings?
I sadly don't have many ideas left :(
