Where Are the Upgrade Files

[yowbooks]

My Ad Seller Pro tells me: "Your Version: 1.0.10 Latest Version: 1.0.12"

I have spent an hour looking for some kind of upgrade download link on this site. There is none.

Is the goal of this product to make you pay a whole new license for each and every upgrade?

You can find the downloads in the downloads forum for Ad Seller Pro contains the latest updates.

There should also be a link there from the licenses button and from the main forum listings.
