Why doesnt Tetris Arena work any more in Tetris friends for PC?

i've tried just about everything, clearing browser cache, deleting hisory, changing browsers, updating flash, messing with the flash plugin for chrome (it has its own version) and while these things seem to work for some, i have yet to find a solution for this.. i downloaded cultris2 (fast paced tetris clone) and have been playing that ever since as well as nullpomino and lockjaw (also tetris clones, that are highly customizable, nullpo also has multiplayer) the facebook version works for me but the energy thing is annoying as well as not being able to set your side to side sensitivity without buying it with their tetris money. likely not the answer youre looking for but after looking for the answer online for a while, its all i got (play a different tetris) sorry but ive given up on getting it to work,

cheers
