Due to a bug, VEGAS Pro 19 (build 648 and earlier) and VEGAS Pro 20 (build 402 and earlier) will not start after 3rd May 2023.

Urgent update VEGAS Pro 20 build 403 has been released to fix the issue. See https://www.vegascreativesoftware.info/us/forum/vegas-pro-20-build-403-emergency-update-available--140781/.

An update to VEGAS Pro 19 is being worked on. In the meantime, try deactivating your internet connection while starting VEGAS, or set your system date earlier than 3rd May 2023.

It's only right that the update patch should play the Star Wars theme whilst installing.
