Question about windows movie maker

I dont know whats going on with my windows movie maker, it will only let me import 1 video into the Collections place, which is a problem because if you want to save it to the computer, all of the clips have to be in the collection, and it will only let me have one in the collection at a time...I am stumped, I dont know what to do. any ideas?

thanks!

I know whats wrong but its to hard to explain.
Sorry. ):
heh.

oh...could you try to explain it anyway? lol.
I dont care if its hard to understand, I'll try to put the pieces together.

if its to complicated then you dont have to, but thanks anyway
