I've had a look at event viewer:
Faulting application name: Groupy32.exe, version: 1.1.0.0, time stamp: 0x5a97f90c
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
Exception code: 0xc0000005
Fault offset: 0x00020a5e
Faulting process id: 0x289c
Faulting application start time: 0x01d3bab63b7f3e5f
Faulting application path: C:\Stardock\Groupy\Groupy32.exe
Faulting module path: unknown
Report Id: 7b0b955f-26a9-11e8-a413-484d7ee0c77f
Does Group have any specific error/crashlog that might be useful here?
