Hi there
I am experiencing exactly the same thing. Have everything else working as expected including loading business processes from Excel and generating word doc, videos from task recording but when I click Build package nothing happens. The button stays orange but doesnt seem to be doing anything. I am able to click other functions and they continue to work although the Build button remains orange. The white paper said it could take a while, I am only testing it with one small process and have left it overnight - still nothing. I will ask a TC to debug it for me. Please let me know if you are able to get it working, I'll let you know if I make any progress.
Also wondering - do you know how to edit the Business Measure - Key Performance Indicators against the Process Group level in LCS?
Thanks
