Hi,
Sorry for the late response.
You need to make sure that the MemoryStream you want to convert to PDF has a valid postscript signature.
If you open that postscript in notepad, does it start with '%!' ?
You can take a look how Stream file type recognition is done here: https://github.com/jhabjan/Ghostscript.NET/blob/master/Ghostscript.NET/Helpers/StreamHelper.cs
