mylemonblue- What I was saying is that Eovia says that if you purchase C4 now, you get an automatic upgrade to C5. If that's the case, then ugrade your Raydream to C4Pro now, and receive the auto upgrade AT NO ADDITIONAL COST to C5 when it releases. I'm not sure if it will work that way, but it might be the 'backdoor' your looking for to upgrade to C5 from Raydream. Good luck!
