The PartL 2010 program (SBEM 4.1.g) is not producing the XML document for Northern Ireland. This is due to an expired SSL certificate.
Checking the projects EPCGEN.LOG file (with Notepad) shows this error message:
Download the replacement certificate from here.
Navigate into
C:\ProgramData\Bentley\Hevacomp V8i\Hevacomp\PARTL2010\pem\
Locate the cacert.pem file and delete it. Now copy the previously downloaded file into this location.
If you are a Design Simulation user, you should do the same in
C:\ProgramData\Bentley\Hevacomp V8i\Hevacomp\PARTL2010sim\pem\
The software should now function correctly.
