Update/Re-install WordPress Installation Failed

Hello,
I’ve experiencing a myriad of weird stuff on my sites since they were automatically upgraded to 4.1.1 yesterday.

In working with someone on a specific issue it looked like re-installing 4.1.1 might have an impact…but, when I try, I get this error:
———————————–
Update WordPress
Downloading update from https://downloads.wp.xz.cn/release/wordpress-4.1.1-no-content.zip…
Unpacking the update…
Could not copy file.: wordpress/wp-admin/includes/class-wp-links-list-table.php
Installation Failed
————————————

I ftp’d in and looked at that path and there is no file by that name – and I have no idea
what it is.

Any suggestions???

Thanks!
Rob
