app store update problems

yesterday I tried to access the app store and was told that to do so I need to update the app. I follow the prompt (clicked 'upgrade'); took me to a webpage, where the only relevant option is 'download it Today'; clicked it and was brought to a page with two links on it: 'View BB app world availiability' which brings me to a list of countries, with no links, and a 'change language' link, witch leads to a page with an "English" link, which takes me back to the previous page.

I can see no way to actually download the software. Please help.

(I have a 9900 and use t-mobile prepaid)
