Replacing a line of text in .ini using PowerShell

Hello I am trying to run a script in PowerShell ISE to replace a line of text in an .ini file. 

(Get-Content C:\ProgramData\Nuance\NaturallySpeaking12\nssystem.ini) | ForEach-Object { $_ -replace "Default NAS Address=","Default NAS Address=BHPAPPDGN01V" } | Set-Content C:\ProgramData\Nuance\NaturallySpeaking12\nssystem.ini

This script works BUT when I run it multiple times the .ini text keeps getting added to the end of the line giving me a bunch of junk.

Example: Ran script 4 times "Default NAS Address=BHPAPPDGN01VBHPAPPDGN01VBHPAPPDGN01VBHPAPPDGN01V"

I wasn't keen on the suggestions above so here's my solution in case anyone stumbles in from Google and finds it useful.

Contents of test.ini

[Other Parameter] = Something
[My Parameter] = What I wouldnt give for a change of heart
[Other Parameter] = Nothing

My solution:

$MyString = Get-Content "C:\Test_Script\test.ini"
$NewString = $MyString.replace("[My Parameter] = What I wouldnt give for a change of heart","[My Parameter] = I gave my heart for a piece of string")
Set-Content -Path "C:\Test_Script\test.ini"  -Value $NewString

Changed contents of test.ini

[Other Parameter] = Something
[My Parameter] = I gave my heart for a piece of string
[Other Parameter] = Nothing

Try this :

(Get-Content C:\ProgramData\Nuance\NaturallySpeaking12\nssystem.ini) | ForEach-Object { $_ -replace 'Default NAS Address=.*','Default NAS Address=BHPAPPDGN01V' } | Set-Content C:\ProgramData\Nuance\NaturallySpeaking12\nssystem.ini

I just try to use a regex to select evrything behind the =.
