No.
Please try this:
1. open a command prompt
2. type "net start npf". It should tell you than the netgroup packet filter
is either running or has been started.
Then, please send a bug report as explained here:
http://www.winpcap.org/bugs.htm
Please use WinPcap 4.0beta2 for the bug report, as the logs are much more
complete.
Have a nice day
