to work around this issue I have taken the payload.txt file and manually encode 
it myself with java -jar duckencode.jar -i payload.txt

Looks like the error is caused by a missing argument for the DELAY command in 
the first line...

Here is the beginning of a payload i generated

DELAY     <- delay time is missing on this row
ESCAPE
DELAY 400
CONTROL ESCAPE
DELAY 400
STRING cmd
DELAY 400
...

I added 400 after DELAY in the first line. Now the output looks like this,

Hak5 Duck Encoder 2.6

Loading File .....      [ OK ]
Loading Keyboard File ..... [ OK ]
Loading Language File ..... [ OK ]
Loading DuckyScript .....   [ OK ]
DuckyScript Complete.....   [ OK ]

after running,

java -jar encoder.jar -l us -i payload.txt

probably a small bug in the script generating the payload...

Just realized that the human error was present...

In my case i forgot to type in the initial DELAY when asked for it (i just hit 
return...)

How long of a delay would like before starting? 
Use Milliseconds (15000 ms = 15 sec) 400   < --- Don't forget this!

Works like a charm now!
