here's my scenario:

got all the tracking done in pro tools and now i'm working on the mixing phase. most of my stuff is done with RTAS plugs, but i have a couple DX or VST plugs that i occasionally like to use. so i generally open the audio file that was recorded in pro tools to an external program, such as cool edit pro, then run the vst plugins on it, and import it back into pro tools after its all fixed up.

for some reason, however, cool edit pro will not output any sound when these .wav files that were recorded with pro tools are opened. cool edit pro plays other audio files (mp3s, etc), and even plays the pro tools .wav audio file when the "preview" button is selected on a plugin .. but not the actual file normally. anyone had this problem? any suggestions on how to fix it? thanks,
