I know this app probably isn't supported any longer, but I really like using it. I purchased it a long time ago now. I move it from tablet to tablet when I upgrade as I really love the handwriting recognition capabilities. Well just got a new tablet and I'm having issues. I get the error "recognizer certificate is expired or invalid" when I try to open a notebook. I'm using ver 184.108.40.2060. I know this is probably pretty old, but has all the functions I need. Any chance to help me out on this please?
