MX Simulator

So for some reason I cannot seem to get erode to work when I'm just trying to rip some laps by myself. I've asked buddies and tried looking up an explanation as to why it won't work but I can't seem to find an answer. As far as I know I have everything typed in correctly in the target line for the properties of the shortcut? ("C:\Program Files (x86)\MX Simulator\mx.exe" --erode 2.0) I have tried changing the value all the way up to 40 and still nothing. Anybody have any suggestions to help resolve this issue?

Does it work if you start a command prompt and run that command from there?

Honestly dude I have no idea lmao, I'm not computer savvy by any means

Press Win + R, type cmd, and press Enter. Then either type or copy/paste the command and press Enter.
