There is no such thing as a "north American version".  Only US versions and Canada versions, in the Win products.  QMac is bi-national ... but not QWin.

SO,  it would appear that you bought the Cdn version of  QWin.  When did you buy it? How long ago?

Here's the refund policy, but if you contact Q  Support they MIGHT just do a swap.
