Sage 50 2014.2 Update Problem

SOLVED

I've use the Sage 50 Premium Accounting 2014 (3 user edition) on my company 

Here is 3 computer linked to server ,that the server already install  Sage 50 Premium Accounting 2014 and installed Sage 50 2014.2 Update,

2 of the computer installed Sage 50 2014.2 Update,that can read the company data,

1 of the computer haven't install the Sage 50 2014.2 Update,so it couldn't read the company data,

But Sage has temporarily removed the update from download servers,How can I install that update or can i downgrade my company database,
thank for help
