Hi, I'm not sure what script you're referring to? But seems like you're looking to control the LEDs by sending commands directly to LEDBlinky, correct? The command you listed looks correct in the syntax so I'm not sure why it's not working. Maybe try with double-quotes around the parameter; LEDBlinky.exe 14 "BUTTON1,R,0|BUTTON1,G,48|BUTTON1,B,0". If that doesn't work, I'll need to see a debug file; turn on the Debug Log option (misc options tab), run your script, then email me the debug.log and/or debug.zip files and I'll take a look.
