I've just realised that it's only the reverb (Nebula3CoreII64 Reverb.dll) that crashes with the red box skins. It also crashes with Scott's Analog console skin (SK_ANALOG_CONSOLE). The Vintage machine skin (30_SK_VINTAGE_MACHINE) works fine though with Nebula3CoreII64 and the reverb one.
The only difference between these two plugins is the settings in the xml file - correct?
What setting could be causing a crash when I use these skins with the reverb - any ideas? Also, why does the vintage machine skin work fine?
