Sorry for the delay in replying.  This file opens fine in Aperio. Here is the tiffinfo ouput.

That's an OpenJPEG error.  We're reading a tile and asking OpenJPEG to 
decode it as a JP2K image, but the tile data appears to be garbage.

Does the Aperio viewer read this slide correctly?  Could you run 
tiffinfo on the file and post its output?
