First of all try to start from C:|Program files\SWSoft\Plesk\admin\bin\ folder (or where is your Plesk is installed) CMD-line utility 'websrvmng --reconfigure-vhost --vhost-name=<problem domain>' and then -remove it from Plesk CP. Or you can use that utility with '--remove-vhost --vhost-name=<problem.domain>' key and then - reconfigure it.
And the ultimate solution is to remove it from MySQL table manually, but it is the worst idea.
