When I try to get to the Goverment Area it Auto Saves ( as normal ) but then it loads and it suddenly stops every time i try when it just have started to load.....
I tried to install a full install but when i did that it asked for disk5???!!!!???
I tried CD1 CD2 CD3 and CD4 but non of em was right.
So just tell me how to fix that if you know plz.

its probably your game when it installed it gimped up. try re-installing it.

I am not promising that this will work, but it has for me in reference to your first problem of game halting when loading an area.

I copy the auto-save to MPSaves and load it as a multiplayer, go to the next area, save, copy that save over to Save folder and load that game. Presto Maxo!!!!!

Give that a try.
