If you purchased a license from me a long time ago, your license might look like a huge long string of alphanumeric characters with no dashes in it, like this:

MXVIN3Fibm1Xck5DRy9Caxxx3ZCTmVOUTIrek0wc1lpc1N2bnpUTUhDdkp3S2NXeHc9PQ==

3.x licenses have at dash in it. 2.x don't. 2.x licenses don't work with 3.x code. I won't bore you with the details, but the change I made is better for you and me both... much better.

If you have a 2.x license I provide a free upgrade to 3.x (Less headache for me.)

Basically you need to know that if you upgrade, I have to turn off the old license(s). If you're doing an upgrade, this shouldn't be an issue.

All you need to do is say go and your old licenses will be deactivated and I'll send you an account login for your new ones. However many licenses you had for 2.x will transfer over.

By the way, most software providers don't provide free upgrades like this. Couldn't resist mentioning it...
