Hello everyone. I am an absolute beginner in networking and this is my first time participating, please excuse me.
 
I need help. I've been using wireshark just fine, until one day, without previous sign, as soon as I opened my wireshark, the message popped up: "The NPF driver isn't running. You may have trouble capturing or listing interfaces." When I started the capturing, a bigger pop-up: "The capture session could not be initiated (error opening adapter: the system can't find the device specified. (20)). Please check that \Device\NPF_{07FF53B1-0035-4ADE-AD22-8067AC2B2905} is the proper interface." 
 
I didn't understand anything, but, reading that NPF is part of WinPcap, I re-downloaded WinPcap, but no use. Then I ran my Italian Analyzer, which worked (although for a long time it has been running extremely slow), which meant (I thought) that WinPcap was not the problem.
 
Then what is going on? Can anyone hellp me?
