OSC doesn't use an actual templating system as such, so there is no universal way of installing a template. There should be a readme file with your template files that tells you what to do with the template files. If you have a problem understanding what the readme file wants you to do, post its contents on here and we'll try to translate it into normal English for you.

I'm no where near Birmingham, so can't help in that regard I'm afraid.
