Hello I need NAC agent in order to access the internet at my school. However, just today while I was browsing the internet I suddenly was redirected to the NAC page that asks me to login and download the agent. Now whenever I try to start up the agent however the agent will show up in my toolbar but disappears after a few seconds and am not able to login to nac agent since it will not boot up anymore. I have tried reinstalling it a couple times but It still only boots for a few seconds and shows up on the toolbar but the agent interface never pops up
