After accidentally removing my HTC Sensation phone from my facebook account settings/recognized devices from my laptop, - My facebook app and htc sense facebook apps stopped working and had an error loading everytime I opened them up. -I then uninstalled the apps and tried to reinstall them, but was unable to find a link where I can redownload htc sense for facebook? Additionally after downloading the facebook app again, it still has the same error. Does anyone have any advice? Thank you all for your help and expertise.
