I am trying to enter an investigation into the judge centre and when I enter the players DCI number and try and search I keep getting booted out to an error page. Can any one help me with this?

Your best option will be to leave Feedback within the Judge Center.

Entering investigations from a recent GP, I was getting an error page when I submitted the investigation at the end of the process - but the investigation was still going in.

This error seems to be much earlier in the process, at a point that I was able to get past without issue a week ago.
