I type my registration keys but the "Register" button does not highlight.

In Kagi's email you will find a pair of registration keys in the following form:

Registration Name/Reference: "iCMS-Your Name"
Registration code: "4545-564564556-4564"

You must type both the reg. name and the code exactly, without the quotes, don't ignore case. You must always inlcude the "iCMS-" prefix in front of your name.

Tipical errors:

Typing in the Registration Name/Reference Field: "Your Name", you ignore the "iCMS-" prefix.

Typing in the Registration Name/Reference Field: "iCMS-your Name", you are ignoring case.
