Hi Babymum, we're so sorry for missing this post!
Can you try using a different browser (like Chrome or Firefox)?
Also, next time, if you need to send us details like your email address or license key, please email us directly at support[at]brillkids[dot]com. The BrillKids Forum is a public place, and we don't recommend posting your personal details here.

ETA:
As an alternative to using a different browser, you can try reinstalling Little Math. If that still doesn't work, please create a diagnostic report and send it to us so we can troubleshoot further.
For instructions on how to create the report, see:
