How can I move "Glyph Designer" on Laptop to the other laptop.

oriflamme

I have one account ( one account = one license to use Glyph Designer, right?）of Glyph Designer.
First, I use the Glyph Designer on a laptop(A) and I wanna use it on the other laptop (B).
So I did the follow steps,

Uninstall Glyph Designer from Laptop A. ←DONE!
Install the Glyph Designer to Laptop B.←DONE!
Activation ←Couldn't…！

Entered Activation Number ← DONE !
However, announcement like this down below is popped up.(in Japanese.)
" You cant' activate anymore by this activation number. Please extend the valid period in order to add to the computer to be supported by "

I didn't find some pull down menu about license（to move or delete… ）
so, checked out and found the same case posted before, but it has not been answered to for more 2years…

Finally, I have asked here by poor English
Please help me!
