Flash and Facebook Apps Not Working "My Vegas"



Flash does not seem to be working correctly with Facebook Games like My Vegas Slots.
The URL asks to install flash, however I already installed flash step by step via settings / plugins and verified that it is working correctly on other URLs.

Is there a way to get Flash to work at https://apps.facebook.com/playmyvegas/?fb_source=sidebar_bookmark
