USER ALREADY EXISTS

One of our members joined using the name Karli at http://vixensmc.forumotion.com/ and when she tries to log in it's saying her username doesn't exist. She tries to create it but it says it already exists. She tries to create it using her email address and it says it already exists. She tries to make username K_a_r_l_i with her email and it tells her the email address is already registered. I'm at a loss. I search for her and I can't find her via username or email address. Driving me crazy lol
