My computer crashed and I have literally lost all my serial numbers. I did not register my sony vegas 8 so I can't go into my account and find it. Is there anywhere on my computer's hardrive that a tech person can pull my serial number from?
You can't. However, there was no need to register on the SCS site and have them store it.
The serial number was most likely on the manual/email. If you contact magic support &give them the email you registered Vegas with they might be able to help. If they don't have that info because you never registered at SCS & don't have the physical sn/email, you're out of luck.
