Problems (again) running macros

Windows 10 Pro, running Sage 300 ERP 2014 PU3

Macros have been working fine for 3 weeks on brand new box, now today I go to run and I am getting crashes of A4WVBA.EXE

Faulting application name: A4WVBA.EXE, version: 6.2.0.3, time stamp: 0x5522d494
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
Exception code: 0xc0000005

Have disabled AV, rebooted, etc. no change. Looks like A4WVBA starts, crashes and the process is killed

Anyone have any ideas?

Only thing I can think of is a new MS update. Had enough apps trashed by those lately.
