I suppose you mean pcap 3.01a as in the subject. Fyodor stated that the 
recommended winpcap release is 3.04a. Would an upgrade take care of the 
problem for you?

I'm sure there is a reason for the change of functions called here. I 
must say that pcap_lib_version() is a much more intuitive and proper 
name to get the version than PacketGetVersion().
