the Pencil File suddenly will not open.  Has before, but not any longer.  I have used Pencil many times, but this problem is a first.  All things check out… I have the data folder and the Pencil file in same folder… but when I click on the grey Pencil file this evening, it states that I'm asking for an Image to Import, which I'm not.  I've noticed for some reason, there is a P2 file in my folder and I don't know when that showed up or how it got there, but I deleted it.  Before I deleted, it still wouldn't open.   I've searched here and on the original Pencil Support from Pencil and no answers for this.  Did I lose hours and hours of work?
