I highly recommend to keep your software up to date and ensure compatibility with last operating system versions and Photoshop versions.
I try to keep upgrading costs very low starting from only 25Euros for Auto Class Composite.
My license agreements advise you to create a backup of the installer for your licensed version to make sure you can reinstall it at any time later because it is only possible to keep the last version in our servers.
For your convenience I have uploaded a copy of old installers to MediaFire and Mega, please carefully check the version you are entitled to use before downloading. For Album DS and Auto Class Composite please check your license date, it is always in the form Year – Month – Day and you may use the last version issued before this date, for example if your Album DS license is 2016-04-06 (upgrade contracts end date) then your version is 10.6 which was released on 2016-03-15 but you can not install 10.7 which was released a month later (2016-05-01).
Please notice that Album DS and Auto Class Composite include one year of free upgrades and your license upgrades contract date is one year after your order.
