Opening a backup on a remote station

Hi,  I am having problems opening a backup on a remote laptop.

The laptop has BV already installed and will open the company while connected to the network.

I have copied the "data" folder to my laptop while connected however when I try to open the company file on the laptop hard drive I get "invalid control file" the file selected is not a Business Vision Control File.

Any help would be greatly appreciated.

Thanks!
