Lost ability to verify

Trying to verify, with prompt and a cache refresh, a service program and it
bombs with (I think):
 
CODE.LOG:

Using WDSc 4, current I think (applied the efix last week)
CAE 5.5 20021118
System is v5r2
workstation is Win2k Service Pack 3 (build 2195)
system is a 1000 megahertz Intel Pentium III
32 kilobyte primary memory cache
256 kilobyte secondary memory cache
512mb Ram
 
Entering via codeedit.exe 
 
It used to work, at least prior to the efix.
 
Any ideas from the code team?
 
Thanks!
