ZAM 7.5 IR16

Running PRU M on ZAM and getting the following errors which occur almost at the end of the Software Compliance Update part of the process:
Error in PRU
When I click on OK (the only option available) the next error is:
[2.4.1300] An error occurred while performing an SQL operation: [begin LC_Post_PRU; end;].

The update has been run manually as well as using the wizard. The errors are the same no matter which method of update is used.

Any help very much appreciated.
