Hello, same problem here..i've tried the latest release (I use an ethernet dsl connection) and once the installation of both urlsnooper and winpcap was complete,the connection just died. Just to be extrasure, i've asked my friend (who has a LAN connection) to run the program on his pc, and everything works fine for him..also,the uninstall tool doens't solve the problem, I had to do a system restore to make it worka again..any suggestion/solution?
