I downgraded to 5.31.2 to solve an issue I was having with Chrome. When I started the main app, it said I needed to register the software. I was a paid user and it knew I had provided a license, so it asked to verify the license, which it did. However, it also said the license would need to be re-verified in 180 days. With Sophos ending support for Sandboxie, I doubt there will be a server out there to re-verify my registration. Is there a way to get around this?
