It looks like the required ContentBrowserPrefix has been modified in the latest update and this will affect anyone updating to 2.01.12 or 2.02.03.  
I have found that changing the ContentBrowserPrefix line to `ContentBrowserPrefix=FMOD` or removing the line entirely in DefaultEngine.ini has allowed packaging to succeed.  
Can you please give that a shot and let me know if that fixes it for you?
