So have been playing the game for several days, yesterday I had a power cut whilst playing.
Now when I go on my saved game has gone there is a blank line and black screen, I can still load the auto saved game but when I try and save it it just cuts out of the game.
This is windows, and I am not very technically minded at all! Any help appreciated, many hours of gaming appear lost at this point :-(

There are at least 9 different games in the MM series that use this sub-forum. Which one are you playing?
