TS4 upgrade b23 to b24 problem

["Leslie G. Glanz" <zsuzsa@xxxxxxxxxxxxxx>]

I am trying to upgrade to build 24 from 23. After the splash screen I
get a message that I don't have build 21 or greater.  Omega Server shows
release:06/29/1999: 4.23. However, Trade Station shows build 16.
Anyone have an explanation for this. I would appreciate any help.
