Hello, i got the same error on this listing i purchased Girl Character 01 · Adventure · RPG | Fab , i can’t add to my UE4 project, the listing is compatible with UE4, as the developer says but i got the error MD-0011-0 when i try to add to a UE4.27 fresh empty project.
I’m getting a similar issue with trying to install 4.27 or 4.26 to open assets that aren’t compatible with 5. I can’t even install 4.27 or 4.26 as ‘could not download install information’ and there’s the error code ‘MD-DL-0’. The issue seems to be downloads involving Unreal 4.xx or something. There are no server issues and I’ve tried a few different network settings on my end.
