With reference to logging in the FamilySearch Family Tree, in a past post, I related my experience with a person who had an LDS Account and had never, to his memory, logged into FamilySearch Family Tree. When he went to FamilySearch.org and logged in, the menu item for Family Tree appeared automatically and he was able to get into the program.
Now I have a comment as follows:
It appears as if access to this new site/application is by invitation only. When I log into the FamilySearch I don't see anything different. There is no FamilyTree link showing on either the log-in screen or the home screen of FamilySearch. When I go to new.familysearch.org I do see a different home page with an invitation to try FamilyTree proudly advertised in the title banner. There is an available link inviting me to try FamilyTree. When I click on this it takes me to my FamilySearch log-in screen. When I put in my credentials it doesn't do anything but stays at this log-in screen. The screen does make a fast flash which makes me feel that it is merely looping back to the log-in screen.There are several possible solutions to this issue. First, is the fact that you may have been logging into New.FamilySearch.org for sometime and not renewed your log in and pass word when those became applicable to all of the LDS online programs. In this case, I suggest re-registering.
There is a help link titled "Having Trouble Signing In?" on the new.FamilySearch.org site. When I click on this I get a pdf explaining that the new FamilySearch will be available to a few invited people on February 2011. Then it will be available to the public at some future date. I believe this pdf may be referring to the updated FamilySearch site but not to the upcoming FamilyTree add on.
You stated you wanted to find someone who was registered with FamilySearch but not invited to FamilyTree so you could find out what happens upon trying to access the site. Well, not real exciting from this vantage point, but I am looking forward to FamilyTree becoming available to all of us soon.
If you have been using the same password to access LDS.org or Mormon.org, then you may have hit the password issue with FamilySearch.org. Frequently, lately, we have had difficulty logging in and staying logged in. Usually, I just try again after a while and it works just fine. If I am kicked off while working, I just log in again. They know about and are working on this problem.
If none of these apply, then start with the help menus and request help. The comment above does not give a time frame for when this occurred and it may have been an attempt made during the change over. I did my experiment on 4 November 2012. You may just need to try again. But before you do, go to LDS.org and try and log in and see if you have the same problem.
As a last resort, go to the FamilySearch.org Help menu (upper right-hand corner of the screen) and find the document called "Gaining Access to FamilySearch Family Tree" and follow the instructions.
Any or all of these might be the problem. Thanks to all for comments.
