How do I get the Ultimate Facebook plugin to work correctly?

Hi,

I have marketpress, new blog template and multisite user management set up using the gridmarket theme and I wanted to use this plugin to allow users to set up stores with their FB account.

I can get it to login in but it doesn't use the default template I set up. It also doesn't have a selection for that from what I can find. I have done numerous searches.

Any help would be appreciated.

Thanks
Jason
