Such a gross oversight on Wolfram's part is unexpected. I suspect that 
unless the problem is fixed in short order that PlayerPro will not make 
it for very long. Given all that I have heard, I would not install it on 
my system. I am just thankful that my procrastination delayed prevented 
this problem for me. I would like to thank all those who quickly alerted 
the group.
