Installed plugin, now netbeans won't start

When I start netbeans I get an error that a file is missing.

File is like C:\Windows\Users\Developer\AppData\Roaming\Microsoft\Windows\ect
etbeans.cluster

Only occurs for 7.4, not for the old 7.2, is thier a way to uninstall plugins manually, or shoudl I reinstall netbeans, or is their another way to fix it?

Switching over to java from labview because I like text based personally.
