Help need!

Hello, I 've got a problem with my FS9 I cannot solve! May you try to help me please?I am flying with A 320-213 from KOAK to KDAL when suddenly the screen become black, sounds and atc window still works, I am trying to change view but remains black. After 20-30 sec. the program crash and it appears the critical error window of FS9. I tried again and again in other location as well, but it goes to block just before the contact tower instructions for the runway approach. Or just after it.;( It was happened before and I reinstalled the program deleting all my add-on(20-25) to get rid of this error. I'd like to avoid deleting and reinstalling everything everytime this error happens.x(Then I install again these adds-on and just after usa_roads (the last one I installed) the trouble came out again. I suppressed it from add on scenery and got back the original folder of namc, name and namw in scenery folder. But the trouble still on.I am using SkyWorld and FSPassenger. I tried to flight without it and with the static clear weather of FS9. But no way! :-hangAny solutions from anybody had my trouble in past?Thank you.:-wave
