Hi Sheila,
Thanks for your interest in upgrading. Happily, we give returning customers 30% off to renew, so it would be the same as if you’d caught the special 30% coupon.
We’re working on getting a schnazzy renewal system in place, but for now if you an email to pro (at) tri.be we can hook you up with a coupon that will get you a new license.
It is possible to go back to an older version, but if you choose to go that route please remember that we are not able to provide any support on an outdated version. Hopefully with the discount renewing will be a good option for you.
Cheers,
Leah
