There is a problem with the URLs that you need to use to download the readings. Somehow the pdf changes the address so that you cannot just copy and paste. Go to my website http://ling.umd.edu/~tlohndal/ and write the name of the file. For 'Boeckx 06' this will be 'boeckx.pdf' so that the address is http://ling.umd.edu/~tlohndal/boeckx06.pdf. We apologize for the inconvenience.
