Options Framework Plugin

I had a theme using options frameworks plugin, and it worked just fine – but when I switched to a new theme from the same company, the plugin now states:
“Your theme doesn’t appear to support the Options Framework yet.

If this is a mistake, make sure that the file options.php is in your theme folder and that you have the correct theme activated.”

…which I don’t believe is the case. I even reinstalled the plugin, but still no luck. I contacted the support team for my theme, but they haven’t responded yet, so I thought someone here might have an idea?

Thanks in advance~
