We sincerely apologize for the inconvenience. After internal verification, we confirmed that h5.0 and h6.0 use different versions of HD Station. When performing the update, the software should have displayed sufficient prompts to inform users of this change, and we are sorry that this was not the case. We will work to improve this in the future.
Based on our testing, uninstalling HD Station and reinstalling the new version should resolve the issue. If you have tried this and the problem persists, please open a support ticket so our Support Team can assist you further. Thanks!
