Help Lost YouTube app after upgrading firmware...

Hi all, firstly apologies as I am new and not sure whether this should be in the apps subsection.

After upgrading my X10 to R2BA023 via the auto update 'over the air' I have lost the Youtube App.

The youTube App now no longer appears on my menu and I obviously get an error on that it cannot play and says device not supported when I try to download the app from ...

Please dont tell me SE removed the youtube app compatibility with this update... And how can I solve it?!

Thanks in advance for any help.
