I have a game put together partly and I wanted to release a beta version but if i get the beta version copyrighted, do i then need to copyright the next version released also?

Send me all your money and everything you''ve ever created and ever will(except under certain circumstances) will be copyrighted to you.(Note: Sending the money is optional, but recommended.)

You can find the answer to your question here http://www.obscure.co.uk/faq_copyright.html
