prety link undefined error

Hi

Just yesterday I notice a decrease in clickthrough on my websites I am using pretty link and when I log in all my links have a grey drop down menu saying undefined, if I click on the grey box it eliminates the message but after a refresh comes back. This is happening on all my sites and all affiliate links hosted on different severs. So its not tracking.

I have deactivated all plugins and still is happening anyone else having this issue if so is there a fix, is there anyway to reload the prettylink core plugin without losing my links? I literally have hundreds so Im pretty freaked out right now.
