If you're using Norton Security Suite unblock it from your firewall. Under program control search for idlemaster and change access to Allow.

I'm using ZoneAlarm and as noted, it was previously working. I double checked and IdleMaster is "Allowed". Something either changed on Steam's end or a Window's update might have something to do with it. Currently running Windows 7 Home Premium 64-bit
I've found a different farming program since my original post. It has been running flawlessly ever since and with better support too.
Thanks for your suggestion though, appreciate it. :)

My Idle Master Portable hasn't been working the last few time I've tried it.
It says I'm not logged in. I go through the process of logging in with Steam Guard, that window closes, another small one pops up to the effect of "Idle Master is saving your information". That goes away and Idle Master is still not signed in.
I re-downloaded IM Portable and extracted it into a different folder. Checked Task Manager to make sure there was nothing hanging from the previous session and then ran IM portable from the new folder with the same exact results.
I've checked the website and can't seem to find anything there or here that fits or would rectify my situation.
Any help would be appreciated, thanks.
fwiw, I've ran IM port for a few months before this, for well over 100 cards. So this was working previously on my system. The only thing that I can think of that might have impacted IM would be some Windows Updates? ni

Idle Master doesn't remember the sign-in info at all. I'll go through Steam Guard, enter code, IM says it's remembering info, that goes away and IM remains not signed in.
A little help please? I have cards I want to drop before the holiday sale. Thanks.

This just happened to me yesterday. Started portable mode (my usual choice) and it ran fine. Checked it a few hours later and it wasn't signed in and has problems doing so. According to games being idled, it only ran for 30 minutes even though I was on Steam for much longer than that myself. idk what's going on. Can't log in any more, the sign-in screen never loads up.

I log into Steam client normally, open up Idle Master and "Steam is running" is checked and "Idle Master is not connected to Steam".
I click on the Sign In link, a window pops up and nothing happens.
I got a prompt from my firewall the first time and allowed it (and checked it to remember).
The 2 or 3 times I was actually able to get to the Steam sign in page took forever to verify my info.
I have yet to make a successful/complete sign in as it's taking 5 minutes or longer (when it does load up) to load up and start the sign in process.

Any thoughts or ideas would be appreciated.

btw, I tried both the regular ver and portable ver with the same results. Have exited and restarted multiple times as well to no avail.

SOLVED: Using the portable version, i ran the .exe file as administrator and that made everything run smoothly and am now idling 30 games.
