For some unknown reason a few times when I tried to update Chrome it gave me one of these errors. http://support.google.com/chrome/bin...&answer=111996
I had to re-install it. https://www.google.com/intl/en/chrome/browser/
The last time it updated fine from within Chrome, Chrome Menu-About Chrome, to version 25.0.1364.97 m. Never did figure out why it would not update before, so try re-installing it.
I have also had Flash stop working in Chrome, i.e., Youtube videos would say get plug in. Flash is embedded in Chrome, no need to add it to it. Not sure why Flash stopped working, may have been from a Chrome update.
Here's how I fixed it:
-if not already, unhide your files. Windows Explorer-Tools-Folder Options-View-Show hidden files
-Go to C drive\User\Your user name\AppData\Local\Google\Chrome\User Data\PepperFlash\11.6.602.167 (yours may be different depending on flash version) Right click on folder, Properties-Security-Edit-Everyone. Tick Allow for everything except Special permissions, Apply, Ok.
