WebEx Network Recording Player Help

[watchntv]

I am in an online course and if I miss a class, I can download the file and play it

I missed and downloaded the class1.arf file
and I'm supposed to use WebEx Network Recording Player Help to play it
but it wont play
It opens the first screen of the file and then stops with a popup that reads
UNKNOWN FILE FORMAT YOU MAY UPDATE YOUR NETWORK RECORDING PLAYER AND TRY AGAIN


the teacher has no clue, apparently I'm the only student who has had this issue
I can't figure out how to update, I did find out how to use previous versions of the player, but did not help

I was told that if I dowload the lectures and the icon of that saved lecture isnt greenish, I my player isnt properly installed
well, the iconsof the downloaded lectures are white, but I uninstalled my place and I tried to use VLc to play the thing and it wont
I dwnloaded the lecture again and it is still white!

what am I doing wrong?
