After KSP crashing on the hour every hour after installing Only 2 Mods,( Kurs camera, and module manager) and the updated 1.2 it was suggested to remove and replace one at a time,it was while these two were removed someone also said check if playing through STEAM as they default to 32 bit, and I was convinced I had chose 64 bit when installing, BUT after checking and changing my desk-top icon for 64 bit ( which I found in the steam folder) and replacing my 2 mode, I have since notched up 12 hrs in two shifts with NO crashes at all. So a big thank you to all members who replied to my query. And one to watch for new Kerbal astronauts. So with confidence restored in mods , The real looking weather looks cool ( looking back at earth) and the Shuttle with the black tiled add- on..
fly safe.
