Glad for this workaround. THIS WORKED FOR ME! WHEW!
I don't like it either but at this point I just wanted to get the program up and running so I can work. I don't have time for all these recent problems. Vegas Pro has been super inconvenient the past few months and its just not cool. Consistent issues like this cause users to consider other software. I really hope they figure this out soon and have a good run of consistent smoothness with the next release.
But THANK YOU for this. I needed this. So grateful.
I can also confirm this behavior, windows 10 latest patch - vegas 20.0 build 402. Already tried the shift+enter method of clearing settings and cache, and a full reinstall. Vegas refuses to open.
Unplugging the ol' ethernet cable fixed the issue. Obviously this needs to be a critical issue.
FWIW if the devs read this - I tried to work some sysadmin magic, but blocking vegas200.exe in windows firewall didn't resolve the issue, so its related to one of the other dll's or executables that phone home at launch.
Given that so many are experiencing this problem and disconnecting from internet mostly enables Vegas Pro 19 and 20 to open suggests to me that something's gone awry with MAGIX's activation/phone home system ... or Y2K has hit 23.33 years later than expected🙂.
I can confirm this workaround works with changing the date and setting it back to current date works. I can't open it in 2023 though, so for now I have to leave the application open for the internet to work at the same time while I have Vegas Pro running.
Hopefully, this is fixed pretty fast tomorrow and we get back working normally.
One of the things involving both the internet and the time of day is "certificates". If a program accesses a service securely, it will check the servers certificate, which is a a proof of who they are. Certificates are stamped with an expiration date. If that date passed, the connection is considered insecure. But if the program can't access the service at all, maybe it doesn't care so much as it does about an insecure connection.
