I've been using vegas for about a year, and this has never happened to me before but now it is preventing me from editing.
Once I click the event fx icon on the audio or the video itself, it crashes.
With the audio it just sends a crashed report, when I click the video one the window pops up, but then entirely crashes!
Whenever I drop an effect, it works fine. even when I click video fx. But as soon as I remove that effect and close then re open it, it crashes.
