Adobe Flash Player

So I have been a user of Adobe for more then 4 years and never had a problem with it. But for not longer then 2 weeks ago something strange happens.
I load it up as normale but then after 4-5 min. i get this

I have tried to fix this but no use...

What could course this to happen over and over again?The game I am playing is called Realm of the Mad God
Im using this link: https://realmofthemadgodhrd.appspot.com/AssembleeGameClient1473962650.swf

Thank you.
