I have long had a problem with PDN freezing when I try to create a new document, despite reinstalling it three times. I brings up the New dialog, then sticks on the hourglass. In Task Manager it is noted as Not Responding.
Have just installed 4.2.12 - same problem. My system is Windows Home 64-bit, Intel I5-6600K, 16GB memory and using the Classic version of PDN.
Just installed a trial version of the MS Store app: same problem
