A few months ago I purchased this app when they had the $5.99 USD sale (I think it is $24.99 regularly priced). They said you couldn't upgrade for free if you bought it for $5.99, but I just got their upgrade for free. I guess they decided against charging those of us who got it for $5.99 or Apple told them they couldn't do it. Whatever the reason it is a great update and app.. I was just curious if anyone was charged for the upgrade who bought it for $5.99. Thanks.
