Problems with TIFF compression

When I scan a large document (tabloid size) at high resolution and save it as a tiff, the result is an unreadable file (using Windows photo viewer, Picasa 3, and Corel X3).  I'm not sure what exact file size causes this problem but the ones that turn out approximately 3.5 MB are readable but the ones that are more than 6MB are not.  I have tried setting the tiff color compression to each of the three options but they all produce the same result.  I know it's not an innate tiff problem because I have other tiffs that are much larger that work just fine.

Re: Problems with TIFF compression

The following example  code demonstrates how to compress TIFF files using the above method.
using System.IO;
using System.Drawing.Printing;
using RasterEdge.Imaging;
using RasterEdge.Imaging.Codec.Compression;
using RasterEdge.Imaging.TIFF;

RasterEdgeImaging Image = new RasterEdgeImaging();
{
TiffEncoder.infile(@"C:\1.tif");
TiffEncoder.Outfile(@"C:\2.tif");
TiffEncoder = TiffEncoder.Group3Encoding;
}
Image.TiffEncoder(@"C:\1.tif", "C:\2.tif", TiffEncoder TiffEncoder.Group3Encoding);
