I've been working on a documentary for about 6 months. It's Over 3 hours long, has about 15 video tracks and half a dozen audio tracks I'd been working all weekend on doing some Foley work on it. Then, yesterday I opened up Vegas and tried to open my project. It crashed with a unmanaged exception (0xc0000005) error message. I tried it again same thing. I thought no worries I'll use my back up project file. Same thing. By this time I was beginning to get a bit worried.
I scratched my head and thought it could be the program so I uninstalled the program and re-loaded Vegas but when I tried to open the program I got the same error. Now I was really starting to bab my self. I can't begin to tell you the amount of work that has gone into this project so far.
Trying to stay calm and wondering if having a cigarette might help (I gave up ciggies at Christmas) I suddenly came up with the idea of changing the name of the media content folder and try opening the project. I got to 25% then said it can't fine a media file so I told it the location of the file it opened. Vegas asked if I wanted to open all the media in this location, I said yes.
Bish bash bosh the project opened fully, unharmed and ready for action.
I don't know if this will work for all unmanaged exception (0xc0000005) error message problems but if it helps some one then great.
