Cannot make work new sites at Wordpress Network

Hi there guys! You cannot imagine how HAPPY am I right now with your new prices! Sadly at Argentina, our peso is a very weak currency and was very difficult to be a member here last months.

My issue now: I have a multisite network @ http://www.lienzix.com

Decided to make a new site for my network (desdezela.lienzix.com), and the fact is it takes me to another website on my hosting (www.conexionsanjuan.com). I do not know what to do! Should I create a subdomain on my Cpanel eache time I wanna create a site for the network?

Thanks in advance!
