That's often caused by software on your machine conflicting with the 
WinPcap capturing driver/library Wireshark uses to capture packets. Is 
there any personal firewall, VPN or alike software installed?

See http://wiki.wireshark.org/CaptureSetup and especially 
http://wiki.wireshark.org/CaptureSetup/InterferingSoftware

You may ask the WinPcap mailing list, as they might being able to help 
you better ...
