IM is having problems downloading https://psteamcommunity.yuanyoumao.com/my/badges/ (or you've finished idling). Assuming you do have drops remaining, it's possible you need to update your cookies info. The info can change mid-idle necessitating an update of the info, just because it was working 30 minutes ago doesn't mean it's correct right now.

Settings.txt is where Idle Master stores cookie info for the Linux/Mac script, and possibly the Windows version.

If you're manually entering the info into Settings.txt I'd log out and back in on your web browser of choice and then copy/paste the updated info. If you're signing in directly through IM, I'd relog through that.

It could also just be an overloaded server and you should try again after a few minutes.

at least according to the image, you're running "start.py" which is the proper method to start the script. Start.py will try to start steam-idle.py, but it's failing because it can't find the file.

Double check that "steam-idle.py" was also downloaded into that folder

What does it say when you run the script?

How many games does your Badges page say have drops remaining? The yellow boxes i this image indicate where to look.

Free-to-Play(F2P) do not give any cards just for adding them to your Library, you must spend 9$US for each drop. Non-F2P games give half (rounded up) the number of cards in the set. Trading/Selling/Using those cards will not provide you with replacement cards.

Yes, that's a limit set by Valve for the trading card system and Idle Master does not circumvent that limitation.

You need to enter the full path to steam-idle.exe, it'll be something along the lines of

Unless you're using the portable version, then it'll be wherever you extracted it.

I thought free steam games didn't give out trading cards, until you purchase something.

F2P games do not. Games received through giveaways/raffles/etc but normally cost money will give cards.

I have Cs:go also 3 cards from the game but there are 2 more but i can`t idle it says "Idling complete".

You only get half the set through idleing/playing. If you want the remaining cards you have 3 options
1) Trade with other players
2) Purchase them off the Market
3) Wait patiently for booster packs

And i have a question: does if i sell card i can idle it back?

No. Trading/Selling/Using cards will not give you replacements.
