I am afraid to reset or use the forgot button because i heard that it will lock your account if i use those button forgot password and question and answer before you can recover your bitcointalk account.
Recovering the account via the security question will lock it for security reasons, as those leaked in the past.
Resetting your password via your email will not, however it will be shown on your trust page.
Also if you want a proof i am the owner of this account i can give you a sign message so that no one can say that this account was hacked..
You can create a Reputation thread, and sign a message saying something like
"today is [date] and I, BitMaxz have resetted my password via email. I am still the original owner of the account".
In that case, you can point trading partners to that thread in case they ask questions about your password reset.
