i recently pretty much finished a shop in joomla 3.2/.0
was harpy until i updated the joomla tp 3.2.1 and now i cannot access the administrator area at all!!!

is there a way via ftp to copy the files that make up the shop with its products and categories and pictures and then just dump over a fresh install f a joomla 3.2.1 site?

if not do you know of anyway to get back into joomla??!

kind regards
