When trying to renew my 9.1 license manually through http://license.sidefx.com/get_nc_license.php, [license.sidefx.com] I get a license that expires in a couple of days, which happens to be my current expiration date.

If, however, I retrieve a license for either 9.0 or 9.5, I get a July 23 expiration, as expected.

Any ideas?

If you try to install a license that you already have and is still valid, the license website will return that license (with old expiry date) for re-installation. You get the same license, since there is no need to regenerate a brand new one. Once this license expires, you the website will regenerate a new license for you, which will expire a month from the generation date.

Also, if you try to obtain a license for different version, and you don't have this kind of a license yet, the website generates a brand new license, which will expire in a month.

Thank you.
