Access old BBO browser 5.2.21 or newer versions

[BFone]

I am able to have full access to the original BBO browser 5.2.21 as my user name: BFone; this includes the full access to maintain my private cc including editing for many years. However, PROBLEM #1: I cannot log in with my original user name: x-xx, that I had registered almost within a year since BBO had been launched. When I log on via 5.2.21 with my user name x-xx, I was always re-directed to a flash internet browser, which still allows me to assign my private cc to play with other BBO members. Recently, PROBLEM #2: the latest internet browser not only cannot provide access for x-xx to use BBO member's private cc, it did not even allow me to assign my private cc to other BBO users and play my cc. Wonder if there is a way to revise and update the BBO member name access list to browser version 5.2.21 and include the user name x-xx, in order to to resolve my 2 problems associated with x-xx."6"][/font]
