Error Message: Invalid File Specified
 

Hello, I just upgraded from 3.8.0 to 3.8.2 today, and after I did, I noticed that I am no longer able to install Products. Whenever I attempt to, I get the following error message: "Invalid File Specified". This happens whether I upload via FTP or the Control Panel, and I checked my upload diagnostics and they're fine. What's going on here?
