no, now the game should auto update to 5.2.2, then you can install the dlc's
you may now also have to re delete the serials file again in the folder
and if you get any errors or they dont work now, also the settings folder etc, but then if you have followed the steps, all should be working
Done that, deleted first the serials file (twice), then the settings folder, but on restarting the game, I saw "New Content" messages for "Rising Sun", "U.S.Pacific" and "Panzerkrieg", but "Rising Sun" and "U.S.Pacific" still stubbornly remain greyed out. I have installed all DLCs I bought separately successfully, and they are registered in the serials file with (I presume) the license key, but there are also "PacificUS" and "PacificJapan" entries, both with the same key entry:
PacificUS5C81g+bUUhyKC8efCqBOsw==
PacificJapan5C81g+bUUhyKC8efCqBOsw==
Something has clearly gone wrong here. Please advise.
