there, I need to update to latest version of Marketpress

Hi there, I need to update to latest version of Marketpress in my Hearts and Laserbeams site backend, but the option to auto update from the backend isn't available. It just says the plugin update is available.

This is bizarre because I've updated it automatically on some client sites with no problem.

It's not a big deal, just need to know how to update Marketpress manually if there's something preventing it from being able to auto update on my site.

Same thing with the WPMU dashboard plugin in the backend of that site, it won't let me auto update to latest version, how do I install the update?

Is it as simple as unzipping the update downloads just dragging the new files into the folders via ftp?
