I updated Nimsoft hub license from "nimbus-v1.0/DEMO Nimsoft/*/200/1-nov-2011/...." to "nimbus-v1.0/DEMO Nimsoft/*/100/1-mar-2012/...." by clicking on licenses in Infrastructure Manager, doing a right click, selecting add license and then adding the license.
Even though the license got added successfully (as confirmed from the dialog box), when I double click hub probe, I still found the older license. I closed and again logged in to Infrastructure Manager with the same user but the end result is same. I am using "administrator" user for all these tasks.
The referred screenshots are copied below.
