I upgraded to VM 4 on my Macbook Air, running lastest version of Lion.  The previous verson of VM was perfect.  I had it setup so all of my user account folders are shared between Mac and Windows.  Now, when I log into Windows 7, my shard folders and tool bars are gone.  I get a network error message telling me that  "Windows cannot access \\vmware-host\Shared Folders."  The details for the error message tell me that the "network path is not available."  If I try to diagnose it I it tells me that I do not have permission to access \\vmware-host\Shared Folders.  This is probably something simple but I cannot figure it out.  Any help would be hugely appreciated.

Thanks,

Dave
