Summary:
I had a CitectSCADA version that was working perfectly fine, and now it is giving me problems. The only change that I had done was install the Kingfish driver. What is causing my system to crash? 

Solution:
This issue is caused by the older version of the kingfish drivers containing an outdated version of the CTRegion.DLL file, you will notice that this will mainly occur if you have a new CitectSCADA version and use an older version of the kingfish driver. This can be simply fixed by copying a CTRegion.DLL from a working version and overwrite the outdated one. If using the default installation folders this can be found in the Citect\Bin folder.
