Hi, I just purchased my copy of this great add-on, but I get constant Windows low memory warnings advising me to close X-Plane, in the worst scenario all my textures go grey, I have 8 gb of ram and a video card of 2 gb vram, I'm using the low res Saab version but with extreme resolution textures in rendering settings, no hdr, no shadows, I'm using Win 7 64 bits. Do I need perhaps some task killer here? Thanks in advance. Sorry if this is covered someplace else. Alex
