Hi 5th Horseman....I cut the cycles back as you suggested and this worked only partially. I then went through the game forum and found a suggestion from you ref.sound. You suggested that cutting the sound might help...It did!! ..Can't say the game now works perfectly but at least I can play it.. It does still freeze but I press alt and space bar and then restore and it starts again after a short pause..Not fantastic but playable..I have now completed day 1...Many thanks for your help...SAL
