What is your newer version?
The parameter is incorrect message is because early versions are not compatible with the later versions, there are extra fields of data in the headers of kma files in the later versions and early versions can't read this data.

Depending which version your later one is it could just be the genre or language fields as extra genre and I think languages were added, 3.321 doesn't understand them and gives the error.


So if you know you have added these extra genre a possible solution is to open the edit dialog in your later version and find the songs you added the new genre or language to and edit them again to one that 3.321 can read. Might be an idea to make them something that might stand out so if you could remember a genre in 3.321 that it uses but you know you would not have used that yourself. Or perhaps set the language to Chinese then you could quickly edit them back by searching the language field.

There are other things that changed so the above still might not work. Unless you have a backup of the files you deleted the only other thing I can think of is to convert the kma files to mp3+g with songverter then re import them into 3.321 or upgrade that version as well.
