After experiencing this myself, it appears that it's a winpcap version problem.

If you go to the source of winpcap:

Winpcap 3.0 works, but Winpcap 3.1-beta does not.

Also note that you have to un-install 3.1 in order to successfully 
downgrade winpcap. You can verify the re-install worked by locating 
packet.dll in your system32 directory and doing a right-click properties. 
The version tab will give you the version number of packet.dll and you 
should see it change after you're done.

For reference, my working version of the dll is reported as by 
windows. This may not be the only working version, but it is one that works 
for me with snort 2.1.2.
