Reinstalling scribe agent on windows 10 x 64

Hello! When I began to work with scribe online I've successfully installed scribe agent on my pc and launched my own dummy conenctor on it. It worked fine. Resently I had to restore my OS because of video driver. When I restored from one of the restore points and logged in scribe online I saw that my agent has a "Heartbeat Failed" status. I went to windows services and tried to start scribe service manually. It didn't start and fall with the following error in windows event log  "A timeout was reached (30000 milliseconds) while waiting for the Scribe Online Agent service to connect". 

A new installation of client falls on start service stage 

The setup ends with this
