I have been using ad-block plus for a while and I noticed that for last couple of weeks, it tells me to install the update. When I select to install and reach to installation screen, the install button is disabled. It just doesn't work (but I can cancel installation). I uninstalled Ad-block and trying to install it but the same problem. Any idea what is going on here? This is HTC One X, Asia edition if that matters. Thanks in advance.
