A few things here. One, if I am reading you correctly you said you use the same information on the forum as the main site to log in? If so, you should NEVER do that. ALWAYS have individual passwords for the two sites.Next, you should keep your discussions with SR Support since you have followed protocol to get back into your account. So far it seems you've only been asked to provide the last bitcoin address you used to fund your account. That should be easy for you since if you are indeed the original owner of the account that you could log into whatever exchange you used, or wallet, and copy that address. Or it should be in the accounts history. If you're unable to do any of this then yeah, odds are you will need to start a new account.
