I know this post is old but I'm posting this for those searching for this solution for "undefined" when registering widgets.

We recently changed domains and had to re-register our licences for Ray. Even though I found the answer staring in my face, it took a while to sink in :)

We're running Dolphin ad-free 6.1.4. Our problem was due to the version of flash installed in our web browsers. During development we were using flash 9.x and recently rebuilt our PCs and installed flash see more 10.x.

We uninstalled flash and installed a version 9.x which we downloaded from Adobe ( http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14266&sliceId=1). We were then able to register the licences.

Cheers
