What version of Vegas Pro 11? How can anyone direct you to a link without the required information?
And if you are thinking that the "Upgrade" from Vegas Pro 17 to Vegas Pro 18 once released, is this "Update", you really are not going to get a lot of Help.
Should you have Purchased the current offer of Vegas Pro 17, with the "Upgrade" to Vegas Pro 18, Vegas Pro 18 has not even been released yet...that would be this coming Monday, 3 August 2020.
