Will my rations still be saved if my trial period or user license expires?

Yes! Any rations you create during your trial period or within the duration of your user license will still be saved, even if the license expires. You will simply be locked out until you are able to buy and activate a working license key.

I bought an initial or renewal license online, but I did not receive a new license key, why?

There is no automated system for generating a license key, therefore, depending on time of day and availability, it may take up to 24 hours from the time of purchase to receive the e-mail with your user license activation information. If you do not receive the e-mail within 24 hours, check your spam or junk folder in your e-mail to make sure that the e-mail was not filtered by your e-mail service. If it is time sensitive, reach out to the contacts listed on the Support page.

When does my license expire?
