Custom gINT Rules causing crash

Hi

We are using custom gINT rules to carry out various validation tasks / calculations on our projects.

It is currently deployed via Citrix using a rather old version V08.30.03.93 but we are trying to test V10.00.00.50 locally to see if we can upgrade the entire system.

The rules all work in the old version and the code can be viewed, but after loading into 10.00.00.50 if you try and view the code from the gINT Rules menu, the program immediately crashes.

Any ideas???
