Today, the maker of the card catcher that is used to import hand histories into most of the major HUDs used for Ignition made a post on the 2+2 Forums about Ignition crashes.
"I’m going to post the solution in here because we get your customers contacting us and they are confused. We’ve been letting people know about this for the past couple of years, but apparently it’s still not clear.
It’s not the card catcher, drivehud or table tamer causing crashes. I’ve posted this up a few places, but hard to reach everyone.
When ignition updates, if you have the ignition card catcher, drivehud, or table tamer running, sometimes resources files won’t update correctly when ignition does it’s auto update. So if you get a notice for an update, make sure to close these first before continuing the update.
If you’re having crashes or you had those programs open while ignition was doing an update, close them. Re-install ignition and you’ll be fine.
I should add an edit that this is in most update cases. Sometimes Ignition does major updates that could cause crashes, but this happens very rarely."
