Conformation emails and user details emails not sending in Mebership

Hi

I am trying to set up Membership but I am having trouble with emails. I am not receiving any emails on sign up such as conformation of email address and also user details.

I am using a plugin called theme my admin. Could this be coursing problems as it allows you to create custom emails for sign ups. Emails work fine for users registering directly with wordpress but receive nothing when using the membership plugin.

I have not set up any communications but looking at the options I can not see a way to get it to send user details after a user has signed up and before the pay and I see no shortcodes for user details. A user might sign up but not pay but I still want them to be able to log in as a free member.

I don't know what I'm doing wrong here. Can someone help me out with this please?
