Unable to enter meeting

[jaing2]

I can't enter a meeting on my computer. If I click 'New meeting' or 'Join', the other three icons except for the 'Schedule' turn gray. A few seconds later, icons' color returns to its original state and nothing appears. Even the error message does not appear. 

I uninstalled and installed Zoom several times and checked latest update status. But the problem remains. How can I solve this problem?
