Hello. I can help you, but I need to know if it´s showing some error messages or something like this.
Do you have access to the hosting panel?
Contact me if you´re interested, I think I can solve it very quickly.
Hi,
I work with joomla for about 2-years and I can help you in this.
If you have the database and/or website files access, so I can help you in this to reset your password.
Best Regards.
