I was going to mention that, but I'm a couple minutes too late. Anyway, for the deck builder, if there's an error, it'll pop up when you start the program. It's a huge window that you can't miss. If you don't know if there were errors, then there weren't any errors.
There's no thread, but there's a wiki for it here:
http://mtg.dragonanime.org/index.php?ti ... :_Wiki_DocIt's a bit dense, but it's really easy once you get used to it. You set it up to use a unique ID if you plan to share the decks you make. You can do that here:
http://www.slightlymagic.net/wiki/DotP_ ... d_Registry Once you've got an ID just for you, set that ID up in your options in the deck builder.
Once that's set up, just start searching for and adding cards until you're pleased with it. There are three things to customize for each deck. "Edit Name" will let you choose the name. "Deck Information..." will let you change the images and personality name (the deck name shows up in the list of decks; the personality name shows up during the duel). Click Build Image and choose an image. To get to the rest of the images and the personality name, click "Edit Personality" inside the Deck Information window for the images, and then "Edit Name" inside
that window. For each image, just click build image and choose one you like for the deck.
Also, just for the record, I can load ALL of the decks currently in the CW Decks folder; there are 276 of them. No crashes. So I don't think too many decks will crash the game. Or, if it will, it'll probably be a RAM issue, so only systems with less RAM will be affected (I have 8GB). But upon checking, the game only takes 418.5 MB of RAM, so that probably shouldn't affect anyone. That means you
should be able to try adding all the decks again.
