problem with creating/accepting codes

What steps will reproduce the problem?
1.on Windows 7: updated Java to version 7. After that not possible anymore to 
create codes or accept offered codes from friends. Went back to Java 6.35, 
problem still excists.
2.on Windows 2000: installed new Alliance v1.3.0 with old Java 6.31. To test 
new Alliance.
possible to create codes but not able to accept any. Created codes can not be 
accepted by friends either.
3.

What is the expected output? What do you see instead?

Trying to connect Windows 7 pc Alliance 1.2.0 to Windows 2000 pc Alliance 
1.3.0. 
Purpose: testing new Alliance 1.3.0 on Windows 2000, before installing it on 
Win7.

creating code on Win2000 and so trying to connect from Win7 gives next error 
log on Windows 7:

What version of the product are you using? On what operating system?

Windows 7, Intel I7 860 CPU, 8G Ram, Alliance 1.2.0
Windows 2000 SP4, P4 2.6 CPU, 1g Ram, Alliance 1.3.0

Please provide any additional information below.

On Windows 7, when trying to create code, Alliance hangs on "please wait while 
your internet connection is being tested"
maybe port check failure?
