Need Help with Template

[ttjewelry]

I've installed prestashop and 3 templates through my host hostgator, but all that is showing in the admin area is the generic template. How do I get the other templates uploaded so I will have a choice. I don't like the generic one. All 3 templates are showing at hostgator, in the themes file. Should I place the one I want to use in another file? All help is appreciated. I have tried to fix this problem for 2 days now. Thanks in advance.

try going into the "Preference" tab and look under "Appearance". You should see at the bottom a way to click current Themes.
Hope this helps because I'm a noob...
