Kezia,

Thanks for your reply.
I will try again tonight~

Hello, I just bought Little Math & Little Reader  this Monday.

I try to install Little Math yesterday...

1.  I put CD1 into my laptop and installed it.
     It shows the trial for 14 days, then I register it with the key in CD.
     Also sign up for brillkids account and recieved a e-mail "New Personal Message: Welcome to the BrillKids Forums!" form Larry.

2.  Then I put CD2 & CD3 in laptop and import the lesson 1-260 in my laptop.
     I have tried some lesson randomly, it is work.
     So, I got back all CD form my laptop and put them back to the case.
     I closed the "Little Math"

After a hour, I open "Little Math" again.
The Little Math front page is dark, and the message box show my lisence is invalid.
All the lesson is disappered, and I can't click anything.

May I know what happened???
