I have the same problem. I UPDATED the Flashplayer to the latest version and have had nothing but problems. I re-installed 3 times. The installation program says everything is fine. I am on Windows 7, using Mozilla firefox.
Everything was fine before the UPDATE.
I would love to get rid of it and install my original settings so I can use my computer.
ADOBE has left us to talk back and forth to each other to try and figure this out, as there are multiple posts with this problem, and NO solutions.
How can we get ADOBE to stop messing up our settings?
What is your operating system, version & edition?
What is your web browser?
What is your Flash Player version?
What means "do not play"; what do you see instead of the expected Flash content?
Windows 7 2011 Home edition
Firefox broswer- latest version.
Flash player 11.3
I went back to flash player 10 due to the fact that all the times which I have installed the new update it doesnt play any videos on youtube or other websites. I have installed it well over four times because my broswer kept asking me which got me annoyed and made me update it. Each time I update it completely and afterwards I go to youtube.. the video doesnt play and shows blank screen or error each time I tried to play it. This has been the only time which I have ever reverted back to the previous versions due to the fact it doesnt work and wastes my time installing and uninstalling it.
