URGENT HELP NEEDED

hello colleagues! I had a problem with my pc and was formated. i copied flight simulator back to the pc but with some certain problems.

1. It freezes during gameplay after about 30minutes
2. There are no gates in the game anymore so no jetways and all sort which makes the airport scanty.

Please I would appreciate any help I can get to resolve this issues.

1-The chances are that your computer needs a cleaning (overheating).
Dust has built up on the CPU and other fans including the video cards.
Clean out the dust and you shouldn't be crashing.

2-Readjust your scenery settings, it's difficult to give advise without knowing your system specs.
