The play button is greyed out so there is no way to do anything but go to the next lesson. I have tried downloading the next version of Little Math but can't seem to figure this out.
If your PLAY button is "greyed out" (i.e., disabled), then perhaps your Little Math is deactivated (are you able to at least select your lessons/presets?) -- can you also attach a screenshot here so we can have a look at it? For instructions on how to take a screenshot, kindly refer to this post:
http://forum.brillkids.com/forum-how-tos-and-faqs/how-to-do-a-screenshot/If your Little Math is indeed deactivated (where the PLAY button and most of the functions are disabled), try re-importing your license key and see if it helps. In case you don't have your license key file anymore, you can download it again by going to Step 2 of this page:

Let me know how this works for you. Will look forward to your Diagnostic Report and screenshot as well.
