Well, if you provided the same level of information to Sony that you put into your post, it’s no wonder they didn’t respond. Think of the millions of combinations of computer hardware/software that could be possible on a given computer. Any two (or more) of these could be in conflict with another.
I understand your frustration, but in order for anyone on this forum (none of us work for Sony) to be able to help you, you must provide the information requested by persons like Graham Bernard (John Rofrano, Mike Kujbida, Stephen Mann, Steve Rhoden, Norman Black, etc.). I’ve seen lots of posts where people are slamming Sony and Vegas as a crappy product, but when the information is given as requested, it USUALLY turns out to be some sort of USER error, or a software/hardware conflict issue specific to YOUR computer setup. Please review Graham’s post asking for more information, then provide the information requested. No one on this forum is getting paid to provide the help they do. I have learned TONS of things from just perusing this site each day.
Take a deep breath, and provide all the information that has been requested by the more knowledgeable persons that grace this site. If you do, more than likely, they will be able to help you arrive at a logical conclusion as to your problem (i.e. Vegas bug, software conflict, hardware conflict, user error, etc.).
