How to 'reset' XBMC

I didn’t like the default skin so I installed Ace. Didn’t look good so I wanted to change to another. Problem however that I see no option to go to the setup menu where I can select another skin.

I tried deleting and reinstalling XBMC, looked thru all folders on the aTV (using SSH) to no avail. Each time I reinstall (with restarts and more) the skin Ace keeps appearing. How to get rid of it?

 

 

 

 

Delete profile folder

And where do I find this ‘Profile’?
