I don't own that product so can't say for sure, but check if you added the right domain to the exception, it's possible that your error might be on a different file/domain than the one I wrote about. Also make sure the launcher itself is not blocked. Additionally, if your issue is about the "Localization.dll.zip" file, it is possible to manually download it, and place it inside your launchers installation folder (there should be a folder named "2" somewhere inside the installation directory, and inside it "Localization.dll.zip" with size of 0 Kb, just replace it with the manually downloaded one.
But this will only fix the Launcher, as after that the game files will be patched too, and you'll get the same error, but with a different domain and different file, so you could try adding that one to exception and see if it works.
