I've just purchased Substance and tried getting the 801 plugin off of my Luxology account. Unfortunately, Modo crashes immediately on startup.
I'm using Windows 7, have Modo updated with the latest service pack. I've also reset my configuration to default. If I drag the substance folder out of ..\AppData\Roaming\Luxology\Configs\ Modo will launch fine, but as soon as I put it back, it crashes.
There's not much feedback. The crash itself points me to check out information in: commandLog.txt but the only thing in that file is:
[ 2-10-2016 10:41:11 | 0.000 9999] Command[-1]: PRE (null), Parameters: (null)
My video card is a Geforce GTX 670, if that's relevant.
