I've tried all the suggestions for fixing problems with passwords. None of them have worked. When I tried the lost password function, it said something along the lines of "Password sent, please check your email inbox." I tried sending it to the two possible email accounts that I put and it hasn't arrived at either yet.
Are you sure that your e-mail provider is not blocking e-mails received from the Combine? If you have a different valid e-mail address, and if you provide your handle, current e-mail, and the new e-mail, someone will be able to change it for you so you can try it with a different e-mail address.
