Hi everyone, I have a question and wonder if anyone has encountered or regulated this problem. I'm new so bear with me

. I'm still editing my project and I noticed that as I put more and more files, it always gives me a sign saying adobe is running out of memory, please proceed with caution. After that the program just crashes. I am making a rather long home movie and was wondering if my project is too big and I should make a new project for a separate DVD. I know that adobe is a system hog but I do have 1 gig of memory and I'll post my specs which last I checked were over the recommended. If you guys have any advice I would really appreciate the help!

Thanks guys,
Ken
