NEW to WordPress

First, I want to apologize in advance for my lack of knowledge with wordpress. I know it is frustrating for you guys who do know and do webdesign, but I would greatly appreciate any help.

I had previously listed a question on Miscellaneous – New To WordPress, approx. a week ago.

I have a webpage that was created by someone else who is no longer available to maintain it and is unable to be reached. Prior to leaving I was given several pswrds/usrn. supposively all of the access codes needed to maintain, edit, change. For several months I have been updating the website Posts – adding, editing and creating Posts (writing posts). However, I need to change information on pages and create new pages. And I am unable to do this or (I don’t know where to go to do this)

I was hoping to find someone who could possibly talk with me and help understand how to do this ( or If I can do this and what is needed) and determine if there is something I am not doing or if I need further access possibly create or edit the admin user info/profile.

One person had responded and mentioned that possibly I was not given all the rights.

I have to step away from my computer for about an hour or two, but would truely appreciate it if there is anyone willing to talk with and could help me, I would very much appreciate your time.

Thank you in advance.
