Hello ! So I just bought a RebornBuddy license key today. It worked fine at first, but after about an hour the app started crashing. When I tried logging back in, it kept saying "Invalid product key" - I tried switching between both China and Europe servers but same error. I've attached the screenshots and logs for you to check. Really hope you can help me sort this out. Thanks!(Oh, and just wanted to mention – when the crashes first started, I was on version 1.0.586.0. After noticing the issue, I actually downloaded the latest version 1.0.681.0 and tried logging in again, but still couldn’t fix the problem.)
