when trying to function on these sites i get the message "couldn't load plug in", followed by "make sure Flash player is installed with default settings." I use an older version of Opera( 36.0.2130.80 ) and flash player is installed and enabled, the adobe site also says I have flash player installed, so when I tried to access the global settings manager on the adobe site i couldn't because plug in wouldn't load so of course changes were not possible....what do I do?
