I purchased WM 1&2 (the combo set) but I can't find them. They don't appear in the original game entry in the library, nor as a separate entry. I have tried updating the game but that just re-installed the basic version (albeit with a space piglet). I have contacted GOG support but all I have received are form lettersm in reply. Any ideas?

Part 2, remembered that GoG downloader existed before galaxy.. Used that and had no problem.. It seems GOG galaxy was this issue, not recognizing that the DLC had been purchased.
