42PFL4007H/12 Can't retrieve a license key

[yovev]

Hello,
yesterday I bought a new 42PFL4007H/12.
Since there was no CD with software in the package, I registered the TV here in the Philips website. I saw I can download the MediaServer software and can obtain a license key for it.
However, no matter what I do and what browser and OS I use, the "Retrieve license key" button does nothing (as shown in the attached screenshot).

I will be really thankful to any help or advice on that issue.

P.S.
I tried the following devices/OS/browsers:
Desktop PC running Windows 7 with IExplorer 9, Mozilla Firefox 12.0 and Google Chrome 19.0
Netbook running Windows XP Home Edition with IExplorer 8, Google Chrome 19.0
Samsung Galaxy Tab 10.1 running Android ICS 4.0 with the default browser
LG Optimus 7 running Windows Phone 7.5 with IExplorer 9

All failed when clicking on the "Retrieve license key" button
