What happens if I don't renew my license?

If you don't want to renew your license after it expires, you can continue to use the version of Superstring that you have, for as long as you want, but you won't be able to receive any further updates. If you decide you want to renew at a later date, you're welcome back at any time.

When will I have to renew my license?

Your license is valid for 1 year after the date of purchase so if you bought your license on Nov 25, 2023, you'll get all the regular updates that are released up to Nov 25, 2024. To receive updates after that date, you'll need to renew your license.

Can I install Superstring on multiple computers?

When you purchase Superstring, your license entitles you to use Superstring on one computer only.
