Adobe Extension Manager or Exchange issues with installing addon's

I am trying to install an addon for Photoshop CS6 on a MAC.

I have installed Adobe Extension manager for CS6 (6.0.8) but the view looks different to what i can find on the website

(NO 32 or 64 after the applications)

When i try and intall Webbsy Trial version I get the following error "an unexpected error occurred while trying to verify this extension.

So then I installed Adobe Exchange 1.2.1,

I opened Photoshop CS6 and then the Exchange.

As you can see, this works but i cannot select any of the options..

when I select one of the plug-ins that is showing it asks me to login.

I enter in my adobe Id and password, but the system does not accept it..

I know my adobe id and password is correct, because I can login to adobe with no issues via the website.

CAN SOMEONE PLS HELP.

THANKS
