Have you restarted steam and idle master, logged both out and back in? (steam 1st)

Yes, multiple times before posting this. I restarted both again for good measure after I saw your suggestion. When I launched IM again, it said I was ingame for a couple seconds but went back to Online. Which happened a lot before. It never stays ingame permanently.

It's been suggested to freshly unzip idle master to a folder on the desktop, might be something to do with folder permissions. Could try that.

Or delete appdata as per pinned discussion.

And check user level of steam and idle master - they should both run at the same privilege level. (see pinned discussio for troubleshooting).

Yep, I've already tried everything in the pinned discussions.

The only thing I didn't try was putting Idle Master on my desktop instead, which you just mentioned. Tried it and it didn't change anything. Games still "crash" back to Online.

One thing to point out is that quickly skipping through all the games still gives me cards. However, I didn't download the program to get cards manually, so I still need help with this.

Archi's steam farm is regularly updated, you could use that instead.

Otherwise the top suspect would be win10 and it being run as win7 and MS dot net version or corruption problem, what version MS .net framework you running? You could try to repair it.

Also rebooting windows (full shutdown) often fixes glitches.

Archi's Steam Farm works for me.

Thanks for the help, I appreciate it.
