@somchai_sittichaisri Which version of Roon are you running 32 or 64bit? Windows 10 Home or Pro? And what build?
Is it with the RoonServer in the background and separate remote or are you running Roon as both Core and Remote as one?
@support the support guys will likely be wanting more info and probably a copy of you logs to. See here I'm having a problem with Roon -- where do I report it?
