Segmentation model HV

Hi

I am running the HV segment modeller and all is OK with the UI except.....

When I select create segment model (new), go in and save - give it a name the name does not appear immediately on the title bar.

The main issue is none of the menu options i.e. generate model etc are available - they are all greyed out.

I can filter on my attributes and create a target group but the options on the top menu bar remain greyed out.

Any help would be great.

Thanks
