Linksys Wireless Webcam Connection to Messenger Services?

I bought the Linksys Wireless Webcam last night and can view it on my
desktop- as well as their site- but it will not show up in AOL/AIM, Yahoo
Messenger or MSN Messenger! I've tried EVERYTHING I can think of on the
"lists of things to do" and I can't get it to work- it still says "Camera not
found"
Linksys directed me to MSN and Dell who won't help....Am I missing some step
in disabling a firewall or configuring the two things together?
Any advice is appreciated!
Thanks!
