Patch Problem

Hi there i have a question i have 3 Problems since the latest Update.
First of all i can't open the Game udater like i always did doubble left click. I have to do an Rigth click on the Icon and click on open as an Admin!
Second and also my third problem i can still play PVP and Hystory missions like Jaburo Base and so on but after i finished an PVP match the game just shut down it self with the warning Acess Violation or something like that and the self goes for the Story missions but i need to be victourios before the game just shut down.
Did anybody knows why this is?
I'm gratefull for every advice you can give me!
