Adobe Acrobat Viewer

Hi everyone. I'm in the edge of suicide... please I need help with
this:

I don't know if you have ever met this Java Bean that let's you
display PDF files it's the Adobe Acrobat Viewer for java that can be
downloaded here: http://www.adobe.com/products/acrviewer/acrvdnld.html
Ok? So:

I'm currently developing a project witch uses the Adobe Acrobat Viewer
Java Bean to display PDF Files, everything was going right but then I
reached a major obstacle that I can't overcome. To display a PDF file
the program uses this code:

    public void renderFile(String FileName, int Page)
    {
        FileInputStream iStream;
        Viewer ViewerWindow;
        Viewer BaseViewer;
        File PDFFile;

        if(FileName == null) return;

        PDFFile = new File(FileName);
        if(!(PDFFile.exists())) return;

        try
        {
            BaseViewer = new Viewer();
            ViewerWindow = BaseViewer.openNewWindow();

            iStream = new FileInputStream(PDFFile);
            ViewerWindow.setDocumentInputStream(iStream);
        }
        catch(Exception ex)
        {
            return;
        }

        try
        {
            Page = Page - 1;

            if(Page < 0 || Page > ViewerWindow.getPageCount()) Page = 0;

            ViewerWindow.renderPage(Page);
        }
        catch(Exception ex)
        {
            return;
        }
    }

Off course the procedure has messages that alert the users about
errors but you are not interested in that right? Ok here's the problem
everything works ok until I call RenderPage, no matter what number I
pass to the function the Acorbat windows always freezes and I don't
know why this is more or less the same procedure used in the sample
program that comes inside the zip.

Any Ideas?

Thanks in advance.
