As Jaime say: You have to copy all files used i the project.
The easiest way is to use 'Pack Projects Material' and save the material i a folder of its own.
Then copy this folder to your memory stick (hopefully your memory stick is big enough - else you must copy the the folder in smaler parts)
Then copy the folder on your memory stick to your new labtop.
This way you won't have messages saying that the file cannot be opened as it was moved or missing.
I've done this lots of times.
