It really looks like there's a permission problem preventing it from saving the files it downloads. I know you said you already fixed the permissions on the map folder, but I still have a very strong feeling that's the problem. Open the properties for the folder C:\Users\owner\Documents\My Games\Gas Powered Games\Supreme Commander Forged Alliance, go to the Security tab, click Edit... and make sure both Modify and Write are checked for Authenticated Users and Users. If it prompts you to choose whether to apply changes to just the folder or to subfolders and files, make sure to select subfolders and files.
