Printer install problem. Heard of this prob?

Just brought home an Epson C40UX and hooked it up. it is USB only and my Win XP Pro recognized it but couldn't find any drivers for it. I didn't use the disk provided as I KNOW there has to be newer drivers on their site. there were. so i downloaded and attempted to load them. all looked to be going well until it told me "there was a problem installing your software. THE RPC SERVER IS NOT AVAILABLE." What the hell is an RPC Server? Anyone? Thanks in advance!
