Program is borked. You'll need to use a different program.

Very unlikely

From the FAQ thread

You can either use cmd or make a shortcut and edit the command-line to do that,
just put the game id after steam-idle.exe
if you don't know how to get game's app id: SteamDB[steamdb.info]
cmd : http://i.imgur.com/fmucN04.png
shortcut : http://i.imgur.com/1kdyCTH.png

You can try, but many of them have failsafes to prevent that from working.

Sometimes the devs forget although.

Read the pinned thread please

Read the handy topic which literally says "Idling complete" in its name, as does your screen

You will have to forgive my bluntness, but seriously dude? You're the 5th person TODAY to report this "bug" which is on the FAQ and has a topic dedicated to it (and how to fix it).

My fellow mod refers to the parts about how Idlemaster is totally FUBAR. You will need an alternative program. Sorry, chummer.

HERE

A steam update has broken the program. You will need to use an alternative program for your idling needs.

Idlemaster has been broken by a recent steam update. You will need to use a different program. This is what my fellow mod, MrLogic, refers to, as we're unsure when, if ever, Idlemaster will be restored to a working form.

Im currently using it again it has been working for a few hours...

*owlish blinking*

Okay I got nothing. So it works for some people and not others.
