Direct Access Statistics.ps1 no longer working?

Hi There,

We have a lot of users working from home and I notice our Direct Access Statistics.ps1 script is not out putting any results to PRTG? This is the script:

 Try {
$DAC = Get-RemoteAccessConnectionStatisticsSummary -ComputerName DASERVER } Catch [system.exception] { } Finally { 
$myxml = '<prtg>' + "`n" + '<result>' + "`n" + '<channel>TotalConnections</channel>' + "`n" + '<value>' + $DAC.TotalConnections + '</value>' + "`n" + '</result>' + "`n" + '<result>' + "`n" + '<unit>Custom</unit>' + "`n" + '<Customunit>MB</Customunit>' + "`n" + '<VolumeSize>MegaByte</VolumeSize>' + "`n" + '<Float>1</Float>' + "`n" + '<channel>Total Bytes In Out</channel>' + "`n" + '<value>' + ($DAC.TotalBytesInOut/(1024*1024)) + '</value>' + "`n" + '</result>' + "`n" + '<result>' + "`n" + '<channel>MaxConcurrentConnections</channel>' + "`n" + '<value>' + $DAC.MaxConcurrentConnections + '</value>' + "`n" + '</result>' + "`n" + '</prtg>' 
$myxml 
}

Now when I run the .ps1 script manually in Powershell ICE it outputs a value correct

PS C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML> C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML\Direct Access Statistics.ps1
<prtg>
<result>
<channel>TotalConnections</channel>
<value>838</value>
</result>
<result>
<unit>Custom</unit>
<Customunit>MB</Customunit>
<VolumeSize>MegaByte</VolumeSize>
<Float>1</Float>
<channel>Total Bytes In Out</channel>
<value>498874.701332092</value>
</result>
<result>
<channel>MaxConcurrentConnections</channel>
<value>844</value>
</result>
</prtg>

Any Ideas?
