Change from Server to Client version on GM Upgrade

[gerfuls]

I initially installed the server version on dev preview 1 and updated along the way and everytime it automatically kept with the server version. Now I'm attempting to install the client version, as this is all I need, but it says I must first purchase the server app from the Mac app store. Is there a way to convert back to client only so I can install the GM?
