Mediocre gone dysfunctional

It worked ok for reading, but marking and filling out the forms was a MAJOR PAIN.
Still kept it, but then Kdan decided that if I want to store more files I need to upgrade & pay. Fair enough.
Except I do not, so I deleted some files.
Now, I cannot access ANY of my files. An attempt to do it triggers an upgrade request.
Its not too much $$$ but I got a FREE app, not a time limited version. So I do not appreciate that.
And I cannot say that I *loved* the original either.
