Well, I finally got it. Just transfered everythign to my laptop (50 mins), made the movie again on Movie Maker (done in no-time, saving took 1 hour). Then added the music to it, as it would get stuck if I made it into one big movie and put the music under it (took 20 minutes to save) and now I'm uploading it to youtube (takes about 50 minutes).
Thanks for all the help, Zero. For some reason, I still can't find my home PC on my laptop, but it does work the other way around. That's good enough for me.
