Adober Air update unavailable

Hello

Since approx. 2 moths I've got a problem with downloading AIR update. New version is probably released but when trying to download it is unaccesilble. When download button clicked the page is redirecting to main site adobe.com. No matter which system is used (Win 7 32 or 64, Win 8 64) or which browser (Firefox, IE) every time "download" works as "return to home page".

What is going on?

Regards
