The controller

public class

Your code looks similar to what Ive used in the past, but below is what I typically use:

    Response.AddHeader("content-length", myfile.Length.ToString())
    Response.AddHeader("content-disposition", "inline; filename=MyFilename")
    Response.AddHeader("Expires", "0")
    Response.AddHeader("Pragma", "Cache")
    Response.AddHeader("Cache-Control", "private")

    Response.ContentType = "application/pdf"

    Response.BinaryWrite(finalForm)

I post this for 2 reasons. One, add the content-length header, you may have to indicate how large the file is so the application waits for the whole response.

If that doesn't fix it. Set a breakpoint, does the byte array content the appropriate length (aka, 30 million bytes for a 30 MB file)? Have you used fiddler to see how much content is coming back over the HTTP call?
