Nessus File Format Change?

[LarryLambert]

Running in debug, here is the error we get:

PS C:\inetpub\scans> C:\Scripts\Nessus_Schedule.ps1

Line 935 of the script:

#region NESSUS FILE PARSING

function Update-UniqueVulns($vulnname, $criticality)
{
if ($vulnnames.ContainsKey($vulnname) -eq $false)
{
$script:vulnnames.Add($vulnname, $criticality)
Write-Debug "Update-UniqueVulns: Added uniqe vulnn to $ vulnnames: $vulnname"
}
}

Something in the format of the Nessus file changed so $vulnname variable is returning null.
