C# Acrobat 8 vs. Acrobat 4

Hi,

I am currently switching the referenced DLLin a C# project from a prehistoric Acrobat 4 to an Acrobat 8 equivalent.
My Question is what dll do I have to use now?

Previousley it used to be done like the following (using the ACRODISTXLib.dll):

ACRODISTXLib.PdfDistiller myDist= new ACRODISTXLib.PdfDistillerClass ();
myDist.OnJobFail +=new ACRODISTXLib._PdfEvents_OnJobFailEventHandler(handle_OnJobFail);
//...
myDist.FileToPDF(inputPostScript, outputPDF, jobOptions);

For the new version it also states in the SDK that the above methods should be used, the problem is that I can not find the same methods in the dll installed by Acrobat Prof 8. What I got is this:

AdobePDFMakerX.Distiller acro8 = new AdobePDFMakerX.Distiller();
//There is no "OnJobFailEventHandler
//...
acro8.DistillFile(inputFilename, outputFilename, promptForOutputName);

So what should I actually be using (or why does the SDK still mention the PdfDistiller) ?

Kind regards!
