I recieve this error message when I was trying to render my work after I adjected my texture in the Unwrap edit.
Blender: Render: blender.exe – Application Error
The instruction at “0x0064bbf1” referenced memory at “0x3f1d2287”. The memory could not be “read”.
Perhaps uninstall/reinstall it?
And, BTW, next time use Support forums…just scroll down the main page until you see a header that says “Support.” 
That almost never does anything.
Shellfish :
There have been many fixes to the render. If you’re running Windows, you can download a CVS (pre 2.43) version from here:
http://www.zoo-logique.org/3D.Blender/compilations/win32blender1711.zip
(I.E. may not dowload the file properly, or you may need 7zip to extract it properly)
You can also file a bug report and send in the problem file here :
