Gonna be a rough one to explain or remember each and everything I've tried so far but figured I'd post on the off chance someone has had this happen and knows a solution or any random suggestion that hasn't crossed my mind yet.
This only happens with one particular project, Vegas is running great on everything else. A fairly short one but pretty rich with effects, transitions, music, and tons of sound effects. The problem is that it hangs at 45% when opening it back up, to the point where I thought it wouldn't open ever, but if ya leave it in that hanging state long enough, 5 hours or more, eventually like magic it will fully load as if nothing ever happened.
I've tried a thousand different things already to no avail. I've loaded it on an external drive, tried on my laptop, same thing. I suspect that there is a bad piece of media and have gone to considerable lengths to try to figure which it might be. I would systematically take out portions, save under a new file name, close Vegas, re-open, would do the same thing. I have also renamed the folder that everything's in and force it to re-find all the assets, that didn't work. I converted just about every sound effect that wasn't wav to wav and replaced them in the project and that didn't work.
Now this is where it gets a little weird. I have a good number of folders organizing the tons of sound effects I have. I'm going off of memory here but if I recall correctly, I had gone through and renamed each folder one at a time and told Vegas to skip those missing bits instead of finding them. One folder I renamed and skipped Vegas popped right open. Obviously I assumed that the culprit was in that folder, however, I one by one changed the name of the individual sound effects that were in that folder, putting an X at the beginning of the name, and would re-open Vegas to try to isolate the the "corrupt" file I assume is there. When Vegas would say there's a missing file I told it to skip, it continued to stall on each and every one. Change the name of the folder their all in, opens fine, change the name of the audio files hangs forever.
I should also add that I made a new project and dragged and dropped all the literally thousands of sound effects onto the timeline, Vegas did that quick and painless, saved it and re-opened and opened without a hitch.
Right now waiting for it to open again, been over four hours. Thankfully I'm patient and not up against a deadline but sure would love to figure out what the problem is if only just to know.
