It looks like the AutoUpdate360Works database @ saturn.630works.com isn't hasn't been updated for all the recent versions. Wanting to test the new FTPeek version, I downloaded the files, opened FTPeek Open First_16+.fmp12 and ran the auto-update... which resulted in my getting v. 1.67 installed, which isn't compatible with the new FileMaker 16 features.

I installed the latest version manually, but you may want to have look at this for others not to loose time over it. 

Hi David,

We have made several improvements to the plugins since our last push. We are waiting until we push a new iteration of the plugins to the website before we update the autoupdate file. We are hoping to push the next iteration early next week.
