That shouldn't be happening (obviously ), try pressing Alt+Ctrl+Del, pressing the "Processes" tab, and closing the process "msgplus.exe", then try and uninstall, if that does not work, then download the latest version of Messenger Plus! from http://msgplus.net/download.php, install that again, and try uninstalling, as some files could be corrupt.
Make sure all programs related to MSN Messenger are closed during uninstallation too.
