Hi, some years ago (2019) I purchased landscaping program ‘Punch! Deck & Landscape’ from punchsoftware.com. I wanted to install it on new computer but on-line registration of license key failed.

Their support said that I need to buy new version and gave me 20% discount.

They seems to not care that purchased software had lifetime license:

“Unfortunately with changes in technologies the registration server that the older programs used were rendered obsolete and thus rendered the older programs (v20 and older) unsupportable. This is why we offer the discounts to customers who have those older programs.”

…

"As newer product is released, they replace the older versions, thus the upgrade systems that are in place for customers who have the older products, so they do not have to purchase new product regularly at full retail pricing. "

Is there any way to fight those assholes? The company is located in US.
