Vegas 15 was working fine until I updated with the newest update. Now it is constantly crashing.
In my case not constantly, but it has been crashing when I tell it to quit. Previous V15 versions did not have that problem on my end, though back in Sony days it was happening quite a bit.
The thing is that it does not hurt any files, so it is nothing but a nuisance: The crash is only happening after I tell it to quit anyway, so the only nuisance is that it asks me to report what I was doing when it crashed.
It helps if you describe what you were doing when it crashed, what sort of media you are editing, what your project settings are, your hardware configuration, then we can go through the steps of isolating possible causes.
