I just created an account to zymic with the host movilmart.zxq.net, but when I try to run in the explorer the site http://movilmart.zxq.net/index.html it shows me the dialog Host not found? can you tell me what else can I do to enable the site.?

Maybe you tried to acess during the downtime of the server. Try now and you will see your site, unless your site is not well configured.
