I have version 14, build 105. I am a casual user and only use it a few times a year. Recently I tried opening the software and it wont open. The initial "opening box" will open for a few seconds and then it closes. Its been probably 9 months since I last used it. I have not made any major changes to my computer in the last year. I was reading the forum and this seems to be not an uncommon issue with several versions.
