Licence question

I came across this problem before, but I forgot the solution and I can't find the post in question here any more.

The problem is, I have a bilingual website, and I need a copy of the weblog in both languages on different sections of the site (same TLD domain).

When I opened the English page I got the following:

Can I have a refresher on how to rectify this?
BTW, I can't log into my admin section, this is the first thing I get and the address bar does not change anything when anything is entered in it.

Thank you in advance.
