well whats wrong when it works for an hour then just stops?
You.
Am I supposed to guess what's your problem? You're not giving me ANY information as to what's going on at the time of the error or what it may be causing it.
Are you assuming I have a crystal ball?
I can tell you this (it may or may not be your problem):
Since the latest patch I have encountered what seems to be a bug in TSM (have in mind the latest version is not supported and the old one will be working increasingly worse as it becomes more and more outdated, until eventually, probably when 5.0 goes live, it'll break completely):
When cancelling, SOMETIMES, the cancel auction button seems to become "unclickable" (normally happens with the last couple auctions left to cancel), and the bot will just get stuck there trying to click it.
It's very random, but it seems the more items it has to cancel, the higher the chances of triggering this bug.
In any case, manually clicking ONCE on the "skip item" button will unstuck the bot, and it will continue working normally.
I encounter this problem no more than once a day, and since 99% of the time I have this running I'm home, I haven't looked into trying to find a workaround (that and because I have other priorities).
If this is your problem, well, you're gonna have to either unstuck it yourself, or just not use it.
If this is NOT your problem, then give me something to try and diagnose it with. Tell me exactly what happens before, during and after it stops working.
