Jul 10, 2016 I've been reading comics on my phone for months now without a problem. I have a cbr installed but can't open my books anymore, everytime I try to open a file it tells me that All apps associated with this action have been turned off, blocked, or are not installed. The only files I can still open are pdf files. Any ideas how to fix this? I've reset my apps to default and tried to delete/reinstall my cbr app as well
