Help Please - my AJAX Register has stopped working!

Could someone please help me.  My AJAX register has stopped working. It won't login even though the captcha letters are right, it allows user names that are allready in use even though checking is activated. It seems to have gone wrong and I'm unsure why.

Have you tried to reinstall? Do you have JS errors on the page? What's the URL?

Hi again

yes i have tried to re-install but nothing.  i'm not sure really what it is but i have a copy of my site from 2 weeks ago - i know i should have backed up regularly - i am going to revert back to that - when i get the time (doing an OU degree and have an essay due in so need to complete that first). i will keep you informed once it is done and up and working again.
also, what may be of interest to you is another of my components that requires captcha has stopped working so i expect that its the same problem - but what caused it i am really not sure.  but when i go back two weeks, before i install anything - each time i install anything - i will make a back-up then i might find out.
thanks
