AVpresence causes Reboot PC !! HELP !

Dear Listers,

I am trying hard to solve a problem of AVPresence Component.

On some computers running Win2000 server or Win2k Pro, whenever I call:  =
"AVteacher_mc.startPublish" =3D=3D> It causes the PC to reboot.. !!!!=20

The same SWF file can run OK on a computer running Win2000 Pro and =
another run WinXP have no problem at all !!

+ I try to uncommment some things in AVPresence Code but it does not fix =
the BUG.. !!!

+ I tried to build very simple app with AVpresence and it run OK on all =
PCs.

+ My FlashCom APP is rather large, having some 5 components and 12 =
SharedObjects. (=3D=3D> I wonder if they can interfer with each other =
??)

+ I added recording to APresence but it surely not the cause of reboot =
!!
