If you were doing OK with website x5 home, perhaps we can help you with why the software seemed to reject your chosen website name rather than you try and find another web site builder? (The chances are, if one piece of software rejects your website name, others may do the same. Do you, for example, know for sure that the web site name you want is available? And, while the web building software may be free, as far as I know, you have to pay to get a website name registered - without that, it's not 'yours').
