unable to build lighting

HI

I have just downloaded UE4 via the launcher and going through the basic starter packages

When I try to build the lighting, it fails straight away.

I have checked the swarm agent log and it gives this.

09:41:16: [Connection] Detected new local connection from same process ID as an existing one, closing the old one
09:41:16: [CloseConnection] Closing connection 4606042D using handle 4606042D

09:41:16: [MaintainConnections] Removed connection 4606042D

any idea how to fix this ???

Thanks
