Insync does not work properly anymore on my windows 10 machine

On my windows 10 machine Insync does only work sometimes, when it feels like it. The rest of the time it does nothing, the icon in the tray is " grayed out " and I can not get any reaction out of it.
On my other Ubuntu machine everything works fine.

A re-installation did not help.

I hope you can help me, Thanks in advance.

Can you send in your logs to support@insynchq.com along with the link to this post so we can investigate?
