Fixed .net?
Checked admin levels?
Cleared Appdata? + Deleted all traces of Idle Master + run it fresh from freshly extracted latest version zipfile?
Rebooted and restarted steam?

Does your steam profile say you're in-game when it's supposed to be idling?

How long since the problem 1st happened? Is steam connected ok, poor connection could cause problems.

And you wouldn't have to worry about trying to run steam 5 times. ASF doesn't need steam to be running iirc.

That'd would probably work but you'd be much better off using Archi's Steam Farm to do that, it's made for it.

If you're uding windows 7 or later then get Idle Master 1.4.1.

I can't support the python version version of idle-master as I'm not familiar with it's working. I think you'd need to be able to code Python to some to some degree to be able troubleshoot and fix "BeautifulSoup([your markup], "html.parser")". It looks lke you need to find some 'html.parser' to get the badge page info into Idle-maaster, but I've no idea how to do that. You could google python "html.parser" + your OS version.

Since you've only got three games, I'd suggest just running them one by one and then minimising them to get the cards, it'd be a lot easier.

What OS are you using? win / linux/mac? which version?

Read the pinned discussions, upgrade to latest idle master version.

No, you need a game that has 'card drops remaining' see your badge page, link in my 1st post.

It's working.

Idle master reads your badge page, the page you see here:

Steam gives the cards(not idle master), it only ever gives half set number of cards.

You need to buy the rest or trade for them:

Free-to-play games do not drop cards unless you spend lots $$$ on in-game purchases od DLCs.
