Launching ifilim.com videos using Norton 2003

I'm a new member so I hope my question is not beneath the intent of these forums:

I am using Norton Internet Security 2003. I am unable to view movies on ifilm.com. Their help info says:

A NOTE ABOUT NORTON SECURITY SOFTWARE: Norton Internet Security (NIS) 2003 and Norton Anti-Virus/Firewall 2003 will prevent the IFILM media player from working. You must temporarily disable the "Security" option in these products in order to play IFILM video.

Understandably I am loathe to turn off Norton. My question is this: If I buy a later version of Norton, will that solve the problem?

Thanks, Ed
