I cant access my account anymore because I couldnt remember my password and I guess I tried too many times.

I cant access my account anymore because I couldnt remember my password and I guess I tried too many times. I am unable to answer these questions as I dont send emails from this account nor do i remember any files I may have created but I have important information in the account and I would like to get my information. Why isn't there another way to verify accounts, I usually access from the same computer that I sent my recovery information from but still can't get my account back. I need help.
