License Key / Serial Number Not Accepted (ATLAS.ti 9)

ATLAS.ti 9 no longer uses traditional license keys.  There is nothing to enter in the program on your desktop; everything takes place in your user account at https://my.atlasti.com.  

Once you create the account simply redeem the license key ("R-....") your received with your purchase,  or the invite code you may have been given by a license holder ("I-....") in the account.  

This is also where you can download the latest installer and/or start using ATLAS.ti Web.
