I copied and pasted the singlecpu line into the target block on my windows shortcut and received a wrong path error. I am sure I am running the most recent update, however I am a pure computer user and do not know much about switches and things. Any help is greatly appreciated.
You are going to have to put on your best 'figure out the technical stuff' hat. I'll try and get you pointed in the right direction.
The 'path' refers to the folder (aka 'directory') that you specified. For example, in what I supplied above, I am using the Beta releases, which get installed in a 'Beta2' folder underneath the main folder the game is installed in. That might be one difference between your installation and mine (are you using a Beta release?). Another is that I have multiple installations. I have one called "War in the Pacific Admiral's Edition" which is the default that the game's installer uses. Chances are that is what you have, unless you specified something different when you installed the game. I also made copies of that to other installations so that I can use different maps and different Beta versions for different PBMs that I am playing with people. That is where you see things like "WITP AE - PBM #2". It is very unlikely that will match the folder name for your installation, because I made it up, and what are the chances that you made up the same thing??
So, making an educated guess, it sounds to me like you copied too much of what I posted. You should have copied only the "-SingleCpuOrders" part. I am guessing that you copied the whole line. If that is what you did, go back to the way it was and see if it works. Then add just the "-SingleCpuOrders" (without the quotation marks, of course), and see if that helps with responsiveness when you are entering orders.
