I have been playing ARMA III successfully since its launch. Starting about 3 weeks ago, I have not been able to enter any MP game. When I choose a MP server, the altis map appears and remains on the screen permanently. I can't alt-tab to desktop. When I ctrl-alt-del to task manager, there is an arma 3 process listed under processes but nothing under applications. There is no arma 3 icon on the toolbar.
I verified cache and reinstalled software via Steam. No improvement. {F23750}
