Does anyone know how to update the M-Files Plugin for Hubshare?

My plugin was set up by the consultants in the RDP and the hubshare admin training was extremely basic.  I now know that the update is something that I need to do myself.  I have read the SETTING UP AND USING M-FILES PLUGIN FOR HUBSHARE and the M-FILES HUBSHARE ADMIN GUIDE and there are no instructions on how to do this.

If any of you have done this before, please tell me how to do it.

Thanks

Irene
