I just downloaded the 0.8.1.2 version and am debugging my script. When I get to the line below I get the message that an error has occured and PowerShell+ exits. My JIT Debugger pops up with the message "An unhandled exception ('System.InvalidCastException') occurred in PowerShellPlus.exe [3776]."
$MyLocation = (Split-Path $myinvocation.MyCommand.path -Parent)
