My old computer crashed and now I have installed CK2 via steam on my new computer. When I start the CK2 launcher the DLCs aren't there. When I clink downloadable content on the steam launcher it lists all the available DLCs and on many on them it says - "you already own this" but there is no way of activating them. I have bought the DLCs via steam. Can I solve this without contacting Steam support?
