Windows version: Plover won't load

After accidentally shutting down the computer before shutting down Plover, it wouldn't run, even after several subsequent reboots. Nothing happened after clicking on the icon; no error messages or instances in task manager present. I searched for all files (non-hidden, hidden, and system) containing the word "Plover", and after deleting them and rebooting, then running plover.exe (which presumably reinstalled from scratch since everything had been scrubbed) it worked properly again. If not possible to prevent this problem completely, noisier failure would be helpful.
