Hamachi: service stopped

Hi,

I'm running on Win 8.1, I installed Hamachi and when I start it I have a self-diagnosi popup and the Hamachi service line is always yellow. Summary below :

Summary report
------------------------

Test name: Hamachi service Result: [YELLOW] -> Service status: Stopped

---------------------------------------------

Test name: Files & Folders Result: [GREEN] -> All required files found

---------------------------------------------

Test name: Driver Result: [GREEN] -> OK

---------------------------------------------

I tried to start the service in the service manager but I have a 1068 Windows Error. Moreover there is no description about the LogMein hamachi service.

Thanks for the help
