cannot receive the usage rights of BetterTouchTool with my BetterSnapTool purchase

I purchased BetterSnapTool about a year ago, and just downloaded BetterTouchTool. Then I found that I can receive a year or two usage rights of the latter application by providing information about my BetterSnapTool. I typed in my name and email address and provided the correct path to the location of the, but the following message does not disappear.
"Selected BetterSnapTool license doesn't seem to be valid"

I am guessing that my Mac is both in Japan and runs the OS in Japanese. well... I know almost nothing about how OS works so I could be totally wrong.

Could someone please help?

Thanks in advance!
