Unable to remove ZxMig

I receive the following error when logging in, yet the ZxMig does not show in the zimlets page. I did try it a long time ago, but removed it, it would it appear it didnt remove fully can anyone tell me how to remove it manually.

Both the com_zimbra_suite_plus (Zimbra Suite Plus) and the com_zextras_zxmig (ZxMig) zimlets have been detected.
Please remove the ZxMig Zimlet.
I've tried to remove using the command line but it just doesn't show , there must be an artifact left lying about from when it was installed a while ago.

Thanks
Scott
