VisionCart - cannot save new shop#

I installed VisionCart (on Revo 2.1.3) to set up a test shop for learning but I cannot get past setting up a new store. The "Save" button is grey even after completing all new store fields. What am I doing wrong?

I thought the same. Make sure you fill out all the fields. Oh yeah and on a side note, make sure you get furl going too.
