It appears that all along it was my antivirus software removing the sh5.exe file as it considered it a threat. I'm now going to re-install and remove the sh5.exe from my antivirus's hit list when it again flags up and see if that solves the issue.

BTW I did turn my anti virus and firewall off during the mod and update installations but it obviously detected it once the antivirus was reactivated.

Note to other people using Steam and possibly others. Once you re-activate your antivirus either remove sh5.exe from any future scans before or after its picked up as a virus.
