Got the latest version, same time sync error. How can I revert to the one before yesterday? I had no issues with that
The time sync error does not stop you from using the application. It is just a notification that your computer cannot reach the time server for some reason. My guess is you have fire walled the port needed. If you want you can make sure Parsec is allowed to send/receive on port 123 so it can sync time.
If you cant connect to the time server now, then you couldn't connect before either. Nothing has changed with regard to it except that it notifies you when it cannot contact the time server after 5 seconds.
If you want to completely disable the time server I can walk you through a config change that will do it. Just send me an email.
