If you get the below error message, it is down to the membership setup.
The minimum join date allowed by the database is 01st Jan 1899 (this is a restriction within Microsoft Windows I believe), the max expiry date allowed by the system is 31 Dec 2099.
Back office will only show Jan 01st 2000 to 31st Dec 2099.
Within the membership setup, if you set it to anything over 200 years (200 years works as that is 1899) you will get this error.
Solution: Set the membership duration to match the valid to and from date length. In this case 99 years.
