Unity not showing updates to assets from asset store.

I have a handful of assets purchased from the asset store. Recently, I updated to unity 5.2, and the assets dont show updates to ones in the project that is open.

I have moved some to the :Plugins" folder to avoid recompilation, would this matter?

Otherwise, what would cause this, and how can I fix it? I have attempted to log out, and relog back in (as well as reinstall unity).

BTW: this is unity 5.2 on MacOSX 10.10.5.
