cant log on using my old password

[uphunter15]

Haven't been able to log on using my old user name and password. I tried to change it then wasn't able to get on at all. I have sent emails to whomever receives them and have only received one message back with my old user name and password. I have countless times went on and clicked on "forgot my Password" and it said it will email me and haven't received anything. Of course, I am on now under a new name but would like my old back. Any help from those who run this site would be appreciated.

Thanks

Chris
