XML Sensor

Hi have this ps script

Param
(
    [String]$fPath
)


$cont = (Get-ChildItem $fPath -File |  ? {$_.LastWriteTime -gt (Get-Date -format "MM/dd/yyyy") }).Count

$xmlstring = "<?xml version=`"1.0`"?>`n    <prtg>`n"

        $xmlstring += "    <result>`n"
        $xmlstring += "        <channel>File</channel>`n"
        $xmlstring += "        <unit>Custom</unit>`n"
        $xmlstring += "        <CustomUnit>num</CustomUnit>`n"
        $xmlstring += "        <mode>Absolute</mode>`n"
        $xmlstring += "        <showChart>1</showChart>`n"
        $xmlstring += "        <showTable>1</showTable>`n"
        $xmlstring += "        <float>0</float>`n"
        $xmlstring += "        <value>$cont</value>`n"
        $xmlstring += "        <LimitMode>1</LimitMode>`n"
        $xmlstring += "    </result>`n"


$xmlstring += "    </prtg>"
Write-Host $xmlstring

If I run this manualy it's ok, but if I can to run this with PRTG EXE/XML Advanded return : Network Path not found

Why???
