Members joining problem

Hi,
I have recently made a forum, and I have got the defult admin account, however I have tried making a new account on my forum. I got to the end of the registration, and it said that it sent a confirmation email to the account which I entered. However I did not get an email, and I definatly entered the right adress from the beginning as I copyed and pasted it. I also checked the junk folder, and there is no sign there. I try remaking another account with the SAME user name, and it says that the name is taken. So I go onto the admin CP, and try deleting the account with the name which I desire, however it says there is no existing user.
Can anyone help?
Thanks

Check here:
Administration Panel > Users & Usergroups > Users > Inactive Users

Thank you very much! Its all sorted now!
