Roborun asking for license, didn't do this on my last computer

Hi

I purchased 20 of the MBL series controllers a few months ago. I have been using Roborun on them for the last few months but yesterday I had to use a new computer, as my old one is out of order. I downloaded Roborun just like I did before but now it is saying I need a license because the size of my program is too large. This is the same program that I had been using and downloading onto controllers with my last computer and this never happened. As far as I know I do not have a license # anywhere, but I purchased 20 controllers.

What can I do?

Thanks in advance
