"Spotty" rendering?

[Xauric]

Whenever I render a song now, regardless of the format, it'll have random missing pieces and sometimes entire segments from the original file. Regardless if I have anything else running, and no matter the song, it'll have random missing patches. Any suggestions/fixes? I'm running Ableton Live 8.1.1, I think.

when you save, do you "collect and save" or do you just "save".....if you don't collect and save, you can lose audio files. not sure if that is the deal....but.

I just regularly save. But it's not the als file that i'm having a problem with, it's the WAV/AIFF I get after rendering that has random missing spots of about 1-2 seconds long throughout the song. Less so with the AIFF than with the WAV.
