Hai Bro, after almost 5 years loosing hope trying to find answer why My Sonar cannot load HS2 properly after upgrading to Windows 10, finally I found your advice of switching the Bitbridge and it works !!! ??? You are my saviour because I have so many unfinished projects using HS2 and abandoned because of My Sonar saving project always crashes if I load HS2. Now I can continue my project. Thank you very much for your advice.. ????????
