[Plugin: Aweber WordPress] doesn't show up under settings

Hi!
I was wondering if anyone knew what to do here:
I tried to install this plugin with the automatic install, but it didn’t work. So I installed it manually, and I finally got it to show up in my plugins list on my dashboard. In order to get it to show up on the plugins list, I had to take the contents out of the wpaweber folder and upload them directly to the plugins folder (instead of just placing the whole wpaweber folder within the plugins folder).
So now it shows up in my plugins list on my dashboard, and it’s been activated.
But it still won’t show up on the right side bar under ‘Settings’.. so I still can’t actually use it, as I can’t change any of the options for it.
This is very frustrating, as I really, really want to use this plugin! Can anyone help me? Thanks!!
