DCOM connection to program 'Synsopos.exe' failed

Application ‘Groove Agent 4 SE’ has caused the following error:

DCOM connection to program ‘Synsopos.exe’ failed.
Error:The RPC server is unavailable.

Did a new build yesterday, X99 with 6800k and now get above messages every 10secs or so.
Fresh windows 10pro install, tried different USB ports, but no joy, installed the latest elicenser, no joy
never had this message before, any thoughts?

Problem solved, overhub caused havoc on the intel USB controller appearantly the intel USB2 and 3 controllers share bandwidth? Now i’ve put the overhub on the Msmedia 3.1 port and all is good.
