SimpleCMS not working anymore...

Hi,

My account was working fine last week. I was able to add site, edit editable zone, edit content, etc...

Now, for no apparent reasons, I can't do anything. I log into the account, I select a website, but I can't edit editable zone and I can't edit content.  The only thing I can do is add a new website.

I tried Chrome, IE9, Firefox and that is not the problem. They all stop working this week.

I have a paid account.
