Want to put back old theme

So i got this new theme installed correctly on my site but somethings didn't workout for it. I wanted to go ahead and put my old theme but when i select it i get the error

Notice: Error: Could not load template /home/cuteterritory/public_html/catalog/view/theme/default/template/extension/module/megnortabs.tpl! in /home/cuteterritory/public_html/system/library/template/php.php on line 23

I don't know what i need to change atm, does anyone know what it may be?

Hii

Login To admin Panel

Then Go to extension -> Module

NoW just Uninstall all that module which is installed by the New theme itself

Then Once Clear The cache

And select your old theme from the system->setting theme option as it is you know i think

Thanks

Let me know what the result plz
