Listen I'm not trying to be mean here, however if you have actually followed the guides properly and still can't do it then you messed something up on your end. Try this guide:
http://allisbrawl.com/forum/topic.aspx?id=144811If you're using regular Riivolution then this should have all the info you need to get it set up. Follow it step by step.
If you try using Gecko you'll need the sc_selcharacter.pac.
Riivo ONLY needs the common5.pac for what you're trying to do. Make sure it's named common5.pac without the en. If you do everything correctly and have your file directory set up right then it will work.
