Voice pack port over from v10 to v9

I'm running RTST v0.10.1.8 and created a custom voice pack (Starcraft 2: Protoss, yeah i'll upload it later). I sent the files over to my friend that is running version 0.9.2.9 and he ends up getting this error immediately when loading the vpk file. http://i.imgur.com/SzywfZL.jpg Yes, he knows how to use custom voice packs. If you need any additional information or you find a fix, let me know.

Version 9 voice packs will work on Version 10, but not backwards.

He needs to update to version 10 by turning beta participation on in options. Or you can downgrade and publish the voice pack from 9.
