You need to contact us directly if you require a response- we are usually pretty good that way. Threatening us, as you appear to have done, is not a nice way to behave
We have not rigged anything. A license includes free upgrades and new versions for a minimum of one year. Unless someone is using a pirated license key, it will never time out and will still work with the version you purchased. We always advise our users to keep a copy of the downloads.
From our records, your license was purchased three and a half years ago. We offer a good discounted upgrade license - please see
