How to re-download and reinstall the Logmein host after a computer crash?

I believe so. However I can neither add computer to my account (no subscription associated) or configure LogMeIn host to add computer, same problem. Seems like the system doesn’t consider that I am an iOS client app buyer and had license in principle permanently through buying the app and not for access (client) via PC. I just want my PC that crashed to work with LogMeIn just as before.

The PC is btw an Intel Compute stick that uses just a few watts, which I brought into use to save electricity as the prices in Europe is pretty extreme, these times.
