My problem is I can't get B9 to work with Interstellar and KW Rocketry without crashing due to lack of 32bit RAM. I have the texture reduction packs installed without success, at least 50% of the time the game will CTD and the logs will show that all of the 3.whatever GB addressable from a 32bit app were in use and there was an error on an alloc or reference to an invalid address. I really hope we get a 64bit version at some point, I love how diverse and well designed these mods are!
