I installed the client software on a few XP machines with both service pack 1 and 2 and they all were OK. Now when I installed it on my laptop (XP service pack 2) I can't open the program? I can install new system fine, I can ping the server fine, but when I try and lauch the program to get to the log in it shows an hour glass for about 5 seconds then never opens up? This is version 4.01.07 Rev 6.3 Client.....
