MySQL Service Will No Longer Start (no replies)

Hello,
I have been successfully using WAMP for months now, until I finally tried to log in to phpMyAdmin. I went through the rigmarole of re-setting my password, which took several tries, but I was finally able to log on.

After then following the instructions found here: [www.wpexplorer.com] -- I tried both methods because the first one didn't seem to work -- MySQL Service will not start. Here is the most recent log:

I am running Windows 10 64-bit.
WampServer 3.0.6 32-bit

Apache 2.4.23
PHP 7.0.10
MySQL 5.7.14
PHP 5.6.25 for CLI (Command-Line Interface)
WampServer icon is orange.


Because I have been working on this for so many hours today, I'm afraid I can't even re-trace my steps any more.

Going to my website, everything is empty (because I was doing everything locally before). Trying to reach localhost, I get an "Error: Unable to Connect to Database" message.
