Game disconnected: client closed down connection.

For the past two days it has been virtually impossible to join any servers. The few times I have been lucky enough to actually join a game it crashes after a few minutes and Windows tells me "Battlefield 4 has stopped working." Are there any fixes that anybody has had any measurable success with? Its a really great game but I'm starting to get awfully frustrated with it. I'm running Windows 7 64-bit, if that is of any relevance.
