I hope that this has happened to someone else, not to be a schaedenfreunde sort of thing, but because you managed to fix it.
It seems like all of a sudden after finished creating a deck in the MtG module my VPT started crashing whenever I went to Test Play or Online play. I get to the part where I load the deck I want to use and click "Start". VPT immediately closes with no error messages from windows or anything. Tried a couple fresh installs with the VPT and module, tried the arcane towers module as well and it still crashes at the same point.
