Help with Help!

Hi there, first time I've taken the "forum" route to find an answer but would be very grateful if anyone can help me.

I have just purchased and installed an upgrade from Creative Suite design Premium form CS4 to CS5.5 and have two issues.

Theres lotes fo new stuff and to get up to speed quickly, I have tried to access the inbuilt help files (e.g., in InDesign: "Help>Indesign Help". Unfortunately, nothing happens except a "TextEdit" error box appears saying:

"Adobe Air This installation of this application is damaged. Try re-installing or contacting the publisher for assistance."

I located Adobe Air on my system, un-installed it using the uninstaller and then down loaded it again from Adobe's website and reinstalled. The error message persists - any help?

Also, as more of an annoyance then a real problem. I had a window "pop up" that offered a free benefit for registering my product with a link to update mt Adobe profile and a link to show what benefits were available (a choice between a new font, a photoshop plug in, 30 days with Lynda.com or a trieal of Adobes magazine.). Once I had updated a couple of small things in my profile I went to chose the benefit I wanted (the photoshop plugin) only to find that none of the links in the window were live, so no way to chose the item and down load it. I've seen another person ask about this in the forums when I did a Google search but unfortunately their answer was PM'ed by an Adobe representative so I couldn't follow their solution.

Appologies if these questions have been covered else where - I couldn't find any reference via the forums search but could be I wasn't using the correct search terms.

Any answeres would be gratefully received.

Thank you.

For info I am running CS5.5 on a Mac Pro (2 x 3 ghz Dual-Core Intel Xeon, 8gb ram OS X 10.6.8
