Hi jlmartinez1
With the new version of JA Platon template, you don't need to care about that theme package anymore.
If you're using latest version of template, you can simply set 'Crypsisb3' as default theme for Kunena:
Then go to Extensions >> Templates >> JA Platon template style >> Add-ons tab >> you can add the pages (or all pages) that you want to load extended styles for Kunena:
