Have got full RCS 64, running on laptop with Vista home. Updated software on APB via RCS64 to 1.09. Device manager shows COM5 and COM6 ports are assigned correctly to APB and the smart sensors i bought - but just won't connect, or if does, then drops off when navigate away from window or after a few minutes. NB, I downloaded free trial of SSDC on same laptop and that works fine with same ports to connect to APB and SS - what can i try to get this working as RCS64 looks better than SSDC. Any help appreciated to one frustrated aficionado!
