Facebook download after EE change

After Orange changed their system to EE my bbm & facebook stopped working. I had to redownload facebook & reboot my phone. After that my bbm worked fine, but I've tried to go onto facebook & the terms and conditions come up however it won't let me press "I accept"... So I can't even get onto facebook. The "I Accept" button changes colour so it is acknowleding that I am clicking on the button however nothing happens. Any ideas? Is it a fault with my actual handset?
