Sony Vegas Help

i was making my first vid on sony vegas and i hit a problem i have no clue how to fix. i made a lot of it over days time and it opened it fine every time. but tonight when i opened it and tried to play where i left off it says a unsupported media type was requested, all the files are wma or mp3, it is the mp3 song i believe that it doesn't like. taking out the song and putting it back in won't work so what do any of you people think? plz!

 

It could be that something's wrong with the song that the Vegas doesnt support, it could be the way that it was encoded. Or the file is corrupted, try to download the same song, somewhere else.

 

but it worked many other times with the same song.

 

Hm. Well, Are you sure something didnt get uninstalled that makes the MP3 File work? Im just taking a stab at this but i think you need a certain codec to get it to work.. hm.. Is Quicktime installed? That might work.

 

Are you sure that the video that you put in wasn't corrupted or anything like that?

 

i don't know why it hates me. just sometimes when i open it it has that problem. if so i have to shut off the whole computer and try again. it works like half the time. but the other times it works fine. i think it is Sony not the song.
