Can i say wtf?
It works perfectly for so many users
Windows XP Service Pack 2 (5.1.2600)
Windows Live Messenger 8.01.0168
Messenger Plus! Live 4.11.0.254
Thats what i have so
a) Youre lagging on the WLM version (not that it would matter)
b) is there some Antivirus youre running or something?
Anything that would stop the script from getting your uptime via system performance. Are you on limited user or something?
