@wolfman - which browser are you using?
Depending where your flash plugin is placed you need to replace it...
Just search in your usr/lib/ subdirectories all libflashplayer.so files.
Deinstall flash via packet manager and delete/rename the libflashplayer.so
Replace it with the 10.1 version from
http://labs.adobe.com/downloads/flashplayer10.html.
Check your current version by
http://kb2.adobe.com/cps/155/tn_15507.htmlWhat version is displayed there? - if its 10.0.something it cant be working and you have the bad version.
