I think you can only have one campaign mod enabled at a time. You start the campaign by opening the career option and start a new career. I recommend starting with the 2nd flotilla you can start in a Type VIIB and upgrade to a Type IXB fairly early. They're based in Lorient from June 1940 I think (dont quote me on that). Although if you have alternative campaigns you know already where and what you want to sail.
