PC system Windows 8.1 64-bit.
FSX+Acc running a number of pay-ware and other downloads without problem (although latest Lancaster from Just Flight also causes crash) .
Crash error message:.
Facility ID 120
Error Code 0x88780078
Strangely, unable to retrieve Faulting Module in Events Log/Admin Events as " One or more logs in the query have errors"
Any suggestions gratefully received
