Lost my Blog?? I really need help

On March 2 I got the following mail from WordPress:
Your new WordPress blog has been successfully set up at:
https://www.successfulinfo.com
You can log in to the administrator account with the following information:
Username: admin
Password: (0ouaaI&nSmE
___________
I worked on my site through WordPress for about 2 months – I have been getting backups weekly. During May I did not log into WordPress.

Tonight (6/11) I tried to log in under Admin and could not. I was able to log in under my profile ebookjl49 but I had to request a new password. After logging in I could not access my blog (successfulinfo.com)
I can access it in the Internet.

What do I need to do? I apologize if I should know. I am a new at this and I do not know where to go or what to ask.

Please help
