Cisco Vpn Client Macintosh Error 51
However, I did find that simply loading the kernel extension seemed to work fine: "sudo kextload /System/Library/Extensions/CiscoVPN.kext" Then I was able to run VPNClient with no problems. I've gotten this error ever since I installed the VPN from cisco. So I restarted the MacPro into the 32-bit kernel (hold 3 and 2 when restarting) and all was working well.
