I cannot tell you what's going on; my guess is that this is a little coordination problem due to the fact that Flash Player 11 is about to be released.
As for now, I was successfully able to download Flash Player 220.127.116.11 from the standard download page. I haven't tried to install it yet; I am waiting for all official download sites (at Adobe.com) to show version 18.104.22.168.
For now I suggest that you download version 10.3.183.10 from the links in http://forums.adobe.com/thread/889580
I will keep an eye on the situation, and publish update information when it becomes available. I will also try to alert some people from the Adobe Flash Player team.
Thanks a MILLION, guy! I'd call you by your first name but I'm at a loss here...
I went to those links and I got my Active-X and my plug-in back. I'm back in business!
You're welcome; glad it worked!
B.t.w. I have meanwhile installed Flash Player 22.214.171.124 successfully on Firefox and 64-bit Internet Explorer; it seems to be working nicely.
Until an official announcement is made, I will keep FP 11 release information in this topic.
Ah, so it IS "Pat"... thanks.
