Would ya be complaining if you had downloaded it for free then it went on the market?

You did not spend "more" in Canadian dollars than you would have in US Dollars......you spent what it cost period.

Note: foreign exchange rates -  X  currency = Y US Dollars therefore Y US Dollars = **X ** currency

The ONLY time fluctuations in the exchange rate have any meaning outside of equivalency is if you play the currency exchange market, the rest is self inflicted noise and confusion.

You bought it, now it's free....stuff happens. Sometimes it works for you, sometimes it doesn't; be pragmatic about the situation...less stress.

Though if it was me I would demand a refund, credit for any future purchases I might possibly consider, terminate my internet service, and sell my computer...probably even have the power and water turned off also just for full measure.

Sure would show those pesky merchants but good for having the audacity to release something for free after it was up for sale previously.
