"A memory allocation request failed. maybe there is no memory available or an internal error has occurred"
I'm getting the above error message and I see this problem has been around for several years (23 similar questions)
I'm using MEP17 on Windows 7, 64bit with 6GB of RAM - and no, removing some RAM is not an option! The Win7 Resource Meter shows this is not a memory problem. I have just spent several days editing a short (under four minute) 720p movie and it won't render. Very annoying!
