Update Version 1.2.1 hasn't worked.

So the description of the update says it fixes various bugs and texture pack issues. This hasn't fixed a thing. Still no access to texture packs, drop down menus still freeze my game and unable to download add-ons. (Such as co-ordinates) Otherwise I've noticed that rain causes snow (I've seen a report for that) and that various achievements (including inception) do not unlock. I've also been following reports for the jukebox issue and its states it has been resolved however, I haven't found this.

I'm starting to get frustrated with this and i'd really hope these issues are fixed soon as i'm beginning to loose interest in finishing my command castle (which I can't do).

Any assistance would be greatly appreciated.
Kind regards.
