Sticking to the relevant points:
- I do have local backups up to 2016-05-24.
- I am not able to access these backups because your policy is that I cannot even install Land F/X without a subscription.
- I do not want the latest version. I want the latest version within my subscription period.
- I do not require cloud support or any technical support.
- I do not want to have one-off free support for the current reinstallation only to encounter this problem next time I update AutoCAD.
- While the refund is an acceptable offer, I have a better solution:
IF reinstall attempt
check subscription version
IF subscription < installer
present incompatibility dialogue 'your subscription only works up to version X.X. go to
http://www.etc.com to get suitable version.'
IF user opens land fx AND internet connection available
IF user subscription still valid THEN provide typical update procedure
ELSE turn off updates and cloud backups and present promo dialogue 'this is what you could be getting...'
This solution allows your customers to keep using your plugin (instead of a competitors'), and allows you to keep your money. It's also how everyone else does it.
If you are moving to a subscription-based software-as-a-service, you need to update all marketing to reflect this. At present, you are selling a product, with a year's worth of service included. The product should remain fully functional even after the service period is over.
If you can achieve this update in under a week, I would be happy to stick with my purchase.
Otherwise I will accept your offer for a refund.
Thank you.
