Flashplayer is using a separate cache to store remote shared libraries ( RSL ) .
It wont be cleared by just emptying the browser cache.

To clear the flashplayer cache go to:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html

Uncheck the checkbox: “Store common Flash components to reduce download times”

This will delete the Flashplayer Cache.

After that check it again and done
