esplanade not working,Stylesheet is missing.

Hello,

I had my site set up on esplanade and it said once i had finished sorting the website up that there was an update so i updated.
The update failed and i couldn’t used that template anymore which would have been fine but… i can’t edit any of my pages anymore. when i get onto the edit page it says there are 0 word count. i can change templates fine but can’t change the edit writing etc.

Please help ??
