So i havent played diablo 3 in months and my friend got it and asked me to play which i was like alright this could be fun again. Well go to launch diablo 3 like i use to (which use to work fine) and it stays on the launch screen continiously asking me to send error reports found by agent.exe which i've tried the following

1) Using task manager to constantly end the process of agent.exe but it only comes back
2) Sending the reports for a while to see if the screen changes
3) Exiting the error reports
4) Mixture of all the above

With no luck
