Nevermind, I still get Empty path name is not legal when unlocking my station.

I had to follow the Portable Mode directions here: https://sourceforge.net/p/kp-googlesync/support/Getting%20Started/ and to note, specifically copy the folder to the Plugins folder and not simply the main folder that KeePass was installed to. After this, the error went away and the plugin worked. When in the main fodler, KeePass ignored the plugin entirely.

I just got the error on the latest version of KeePass (2.3.6 as of writing) and the plugin (3.0.1 as of writing).
