Installing theme

[trigger39]

Hi guys, apologies if this has been posted before, i've had a search and can't solve my problem.

I have been using phpbb and am switching to smf, the problem is i have downloaded a theme and uploaded it to the themes folder on my server. When i try to switch the theme in themes and layout it isnt listed in the drop down box.

any suggestions?

thanks in advance
