my problem is solved, i have to wait along 1.5 hrs to get 1 card .-. and 2hrs it will complete the drops

K thx for help :)

because it's not only one game, i've still 20 games left for idle, i changed game to game, but no result, unlike before, i always got 1 card every 20-30mins, i think my program is working unnormally :(

some games that i idle:
L4D2, Hitman Absolution, BEEP, Battlepaths, QuestRun, Tropico 4, Magicka, Mount & Blade Warband, etc

and i think a game like questrun, battlepaths, etc will earn drop for only a short minutes

i have no problem from i've downloading idlemaster until today
my last cards today was Polarity (i got it 3 hrs ago) and from 3hrs ago, i'm idling any games up to 1 hour, but i got no any cards from idling

unlike usually, i got card every 20-30 mins
and now i can't get any cards from IM even i idle my games up to 1 hour

any help please?

anyway sorry for bad english
