Server instance issue

[zibin2k2]

Hello,

I am really scratching my head with server instances. Sometimes when i want to add a server instance(through MySQL server instance config), I fail to add and receive either an 'error0' or 'data directory was not removed automitcally' error. (I have a feelng the second error was because i uninstalled an old copy of MySQL)

I assume that my server instance add process have failed. However, the next time i restarted my PC, i can actually view the successfully created server instance in the MySQL server instance config delete choices.

Well, I was happy that the service was created despite the oddity. I then tried to open MySQLAdministrator and i can see the server running for few seconds before it shows the server has stopped, i tried restarting the server but without success. Whenever i open the MySQLAdministrator panel, i see the service running a few seconds before it stops again. I close MySQLAdministrator and reopen to see the server running a while before stopping again.

Why is this happening?

I have done several unistallation. And if this problem persist, i will have to do it once more. But is there anything else that is not removed from uninstallation that is hampering my progress?

Advice are greatly appreciated.
