Ghost 15 - No NIS 2010 LiveUpdate after restore

This is the second time, the first time I just thought it was a one-off.

 

I restored my PC today from a backup (incremental) I made yesterday. When it rebooted, the One Click support from NIS appeared and mentioned a problem with LiveUpdate. When I opened NIS, it stated no LiveUpdate installed. I clicked Run LiveUpdate and it proceeded to download and install it (56MB).

 

When I installed Ghost 15, I selected the option to install LiveUpdate as well. Would that have uninstalled the existing LiveUpdate installation (NIS)? Do I do another incremental backup to include the newly installed LiveUpdate?

 

Thanks in advance.
