Local version 3.0.4 no theme with Local WordPress version

Was having trouble with database table info in ver. 3.0.3 now my local/sitename doesn’t include my paid-for theme or any of my site’s content after download.
I loaded the TWENTY SEVENTEEN theme just to see if I could get to my “Creativo” paid theme but no joy.
I have my theme folder locally and would really like to get my site here on Local to make the adjustments offline here.
I tried a different install and got “Your wp-config.php file has an empty database table prefix, which is not supported”.
Any help would be HUGELY appreciated.
Thanks for Local.
