Game becomes unstable

[chazbrew 0]

 I have downloaded something and now the game has become unstable.  will play for a while and then the game screen fragments.  The long solutions is to take out the downloads in small groups until it is isolated.  Thought I would atleast ask if someone else has experienced this problem and if so what was your solution.  Work the game on an Imac and has worked fine until now.  Thanks for your considerations.  Chaz

There was a solution to the issue, I work this game on a 24 inch Imac machine and have done so for over three years, no problems until this. The problem actually originated with the imac and the graphics board. Took it in only to find out that the imac was 40 days past its 3 year warranty period. However, The Mac People, not only put in a new graphics card but also a new logic board for no charge! Now that is outstanding service. Try that with your favorite PC. The repair took two days. The game plays fine.....This is why I play on a mac....Chaz
