I wrote a ticket on this and support sent me my user name and key. I noticed that it was different than the one I used. I was trying to use my RM3 key by mistake. When I used the RM4 key it worked fine. The difference is that the RM3 key is only 2 sets of 4 digits instead of the 3 sets of 4 digits uset by RM4. So since I didn't type in a large enough key the Unlock botton stayed grayed out.
Thank you for the suggestion, but I already tried that and no difference.
