Currently blueball_freestackresponsive_v2.0 2.3 is the latest version but RW7 does see it.
Tried contacting Blueball re. version for RW7, but get Mail deliver problem for blueballdesign@gmail.com on their contact page.
Anyone else use this theme and what they now use.
I’m sure that @blueballdesign will be along in a minute to sort you out! 
If you would email us direct on this I will be happy to help you out. The FreeStack Responsive theme works fine with RW7.

Charlie
If you’re trying to update your theme, you should know there’s a bug in RW7 which prevents you from either deleting the old version or updating to the new one. I posted a thread about it (and what worked for me) here:
thanks - they just have.
Your support page http://blueballdesign.com/support/index.php is still broken, I will use themesupport@blueballdesign.com
Hi Charlie,
My apologies yes it now works. I was putting the theme in the wrong spot. I’m now just opening the theme with RW7 and it puts it in the theme folder.
Sincerely Mr David B Gibbins
