Problably not, i think its left from the old versions of lspdfr and doesnt have any function, but deleting it somehow worked for me personally. Alhtough my RPH launches correctly now, Lpsdfr crashes when load it in game for some reason, so if you have plugins loading automatically on the startup screen then maybe you could try "Dont load any plugins" in the RPH settings tab which you can enable by pressing the settings button on startup. This way you could see if your RPH works and lspdfr is to blame, or if the problem is still with RPH.
