communicating with boinc client. please wait...
exit boinc manager or cancel
why my boinc manager keeps closing? any help thanks
I think your AV/firewall is blocking it from accessing the internet.
Try to do an exception in your firewall for all boinc exe files (C:\Program Files\BOINC)
There are few of them there.
If that don't helps, i would if i were you, completely uninstall AV and turned off the firewall just to see if that
solves the problem.
