Cards aren't infinite. After a while your drops will deplete to 0 and you'll have to buy more games to get more cards.

They can ban you for any reason including them just hating your face.

But I've not heard of anyone being banned from using idle master. Occasional people who claim it did, but those people always have all csgo achievements and a profile of people cussing them out for hacking, so I'm sure it was absolutely the program which nobody else has been banned for and not the hacks.

TL;DR nope, you'll be fine. I've even seen people log into vac servers with idle master active and be fine (although I advise against pushing one's luck through this stunt)

it dosnt work :(

That's because he's telling you to read the link. Idlemaster is working fine. You need to obtain more valid games. Go buy game bundles (such as humble bundle or indiegala), look out for giveaways (here's an updating list) or just outright shell out money for games you want. Idlemaster has done its job. Your "error" amounts to "I haven't put any fuel in my car and it stopped working". So our solution is thusly "put more fuel into your car". Idlemaster has run out of valid games to idle. So give it more games to idle.

Idle Master says "Idling Complete", what do I do?
Card drops aren't unlimited - this message means that you've reached the end of your available card drops and Idle Master has no work to perform. The only way to get more card drops is to purchase more games that support Steam Trading Cards, spend $9 in a F2P game (see below), or wait until the developer of one of your existing games adds support for Trading Cards.

All right there in the FAQ.

Reboot it. Sometimes it glitches and misses a thing. Or 10.

That's impossible since the actual "card drops" are on steam and are based on your game-time. So short of contacting Valve and going "Hey guys can I have my card drops without playing the game?" (and likely being ignored) there's nothing else which can be done.

Sorry.

Anyway to find out if they hAve trading cards?

Check their steam page. There's a tag for cards. It should be on the right, alongside stuff like "Controller support".

Keep an eye out for pretty much any "giveaway" games. Stuff like Pixel Puzzles (there's like a dozen varients of that game so they seem to give away on rotation) or games which are on greenlight as "vote for us for free copy of game", if you're willing to stoop to that level of unscrupulous.

There's groups dedicated to giving notice about such giveaways. Just search "Giveaway" in the group listings and you'll probably find 20 in as many seconds.

True "Free games" like TF2 won't give you cards efficiently unless you're the sort of person who buys TF2 keys (or whatever the game in question's equivalent is) in bulk, since it's every $15-$20 USD that you get a free card as a bonus. With each card worth about 9 cents in USD, you can see why this doesn't work nicely.

I's which games you add not how many.

Stop being cheap, spend some money and actually buy games flagged with cards.

Or if you insist on being cheap, stop being lazy and go join giveaway groups.
