How to connect Client!

I just got Client 1.45 and 1.20! Thank for helper!

you may have all the server programs running, but it doesnt guarantee that is propery configured (happened to me once). triple check the .ini files and odbc entries. double read the title of each application when setting up the ini files.

in which point you cannot connect?
what happens if you type an invalid username/password ? nothing? or can you see the server list?

if you have problem with the ftp updater, you should try 1) run your own ftp server in case you dont have one or 2) if you have one and updater still complains, try poiting the updater to a running ftp server on the inet. you will have to touch vn.ini to match the latest_version.txt on the ftpserver but thats not a problem.

oh! now I can connect to Client But I have been Disconnect ! WHY ? How Fix!
Help me!
