Cant play??

I cant play either ever since the legacy client bs .... prior to the switch never lagged now every game every 15 seconds i lag for 5 solid seconds .... everything is in low spec now (was high) client closed option checked still lags like shit i will leave every game mid game until this bull shit is resolved

Go to the installer and run it. From there it should give you options along the lines or uninstall, and repair. Select the repair option and let it run. If that doesn't fix it try completely uninstalling and then reinstalling the game.
