ok. so im making a video in windows movie maker. i have the pictures that i want(btw, its kinda a slideshow). anyways, i want to add audio to my video. it is in wav. format, and i looked on this list of audio types that windows movie maker will allow. and wav. is on there but for some reason it doesn't work. i imported it. then i dragged it into the audio/music column in the timeline view.

this song in wav. format is from adobe audition 3.0 (i dont think it would really matter. but it's a program that allows u 2 make instrumentals.). but anyways, is it because im trying the program out with a free trial? and maybe that's y it's not working?

so any help here?! or any suggestions or personal experiences? plz help ASAP!!! and best answer wins 10 points!!!
how do i convert the song to an mp3. format? and the adobe audition 3.0 costs a lot of money to buy, so is there any other way that i can do this?

I have windows movie maker too. you should download it then you have more time on it and you can put you audio on there. hope this helps...
