So I would like to purchase a legacy version of windowblinds (for example v. 3.4) and when I tried submitting a ticket to stardock they just responded that the ticket is not a valid one. Any idea who I should contact and how to possibly purchase an older version?
If you purchased any older version, they would still be on your account.
That said, we cannot make older versions available for sale if you did not.
