Installs fine but "move" blocks breaks page

Permalink
I installed concrete5.3.3.1 with no problems. All seems to work apart from 2 things and i'm not sure where to start looking.
When you go into edit mode, click a block and choose 'move', the page reloads without the structural css i.e. divs are full width, one above the other (& moving doesn't work).
The other thing is I can't change the admin password. When I try it kicks me out to the login screen.
Any help would be much appreciated! For testing I set all files to 777. Everything else works so far.

Answer: don't try to install concrete5 into a subdirectory. It has to be in the root.
All works fine now - what a great app.
