Can't write posts – Visual Editor not working

Hi.

I was using wordpress.com and finally yesterday I took the leap to ww.wp.xz.cn.

Set up everything with my host and chose a theme. Customized the header and was off to writing posts. But I can’t write posts. The visual editor doesn’t show up.

I browsed online for solutions and here’s what I’ve tried:
– turned off all the plugins, which at the moment was only the wordpress importer – still the same problem
– tried three different browsers and also Windows and MAC OS
– deleted cache completely on all browsers
– switched to the Twenty Twelve theme
– checked to see that my user is an admin
– enabled and disabled the visual editor in my profile

And nothing worked. Please, I need URGENT help as everyday I don’t have my website running is money I’m paying my server and not using it!
