Cannot dauthorize all computers in iTunes nor can i authorize as it states I have more than 5

Question

I recently purchased a new laptop as my old one died. I tried to authorize it to apply updates however it states I have already authorized more than 5 computers.
I read in the help files that you can deactivate all through the store option, however it does not show up for me. In another post i read that it only shows up if you have more than two activated devices.
So I'm stuck. I don't have the option to deauthorize all nor can i authorize becuase it thinks i have more than 5.
Additionally, i have never used the deauthorize feature. since having owning an iTunes account and i do not have access to the other computers as they are all long gone. I've also logged out and back into the account to make sure that wasnt an issue.
Any help would be greatly appreciated.

Click on iTunes Store (top center of iTunes screen), then Account (under MUSIC LINKS on right of screen).  Enter your Apple ID and password.  On the next screen the last entry under Apple ID Summary should look like this:
If you don't have access to some or all of your authorized computers you can click the Deauthorize All button, then reauthorize those that you're currently using.  I don't recall there being a scenario where Deauthorize All would not appear based on the number of authorized systems.
