Default Admin Email not the right one with Appointments+

Hi,

I recently had a site called fight4cash.co.uk. This was my test website before I bought my new domain and went live with my new website.

My host has copied everything to my now live site. treatmeathome.com

However whenever someone makes a booking in appointments+ the confirmation and reminder emails are not being sent from my default wordpress email admin. They're coming from my old admin email (ema@fight4cash.co.uk)

my host believes everything is ok at his end.

Interestingly the order email is coming from my default wordpress email. I should also point out I've tried deleting the appointments plug in and reinstalling it (which took a while) only for it still not to work

Help!

Thanks
Kieran
