I also recommend http://onlineflightplanner.org/ It uses routfinder which inherantly always uses the latest airac cycle and it's all free. Online flightplanner will also generate your fpl in a wide variety of formats.
A word of warning though with "all" these flightplanning programmes including PFPX. They will always try to route via airways. So in this case where a direct flight does not use an airway they will generate a very circuitous route. The fpl I provided above is direct and doesn't use an airway so if there are no airways present on your A to B flight it's a case of manually adding the waypoints.
