That error is because your character is wearing an item that came out after 5.2.2 was released (and so it doesn't exist in the files for 5.2.2).
If you still have access to your account on your phone, you can change your clothes to something older (just try the normal school robes to be safe) and make sure that your hair, accessories etc... are older as well, and then you should be able to log into the 5.2.2 version on bluestacks.
