Error with WinPCap installed.

When I install WinPCap on my windows xp it starts up then freezes.
When I have it installed on my windows 7 machines it works fine, is there anything I can do other then upgrade to windows 7?

Here is the error log:

Looks like it’s freezing on the network information, actually without WinPcap installed, not with. Either install WinPcap or disable the network tracking in the client by running it via cmd.exe with: “whatpulse.exe --disable-networking” (without quotes) in the directory you installed it.
