Could you please take a screenshot
of your Defense + Events, which are found by opening CIS and navigating to Defense+
-> View Defense+ Events
? You can then upload it here
or click Additional Options...
when posting and attach it. Before taking a screenshot, make sure to maximize the window for the Defense+ Events so that the file paths won't be truncated. Once we know which file is causing your problem it'll be easier to create a rule that solves it.
