Check the JTAG connections from your programming header to the device are correct. 

 

Check your CPLD is powered correctly - with the board powered take a multimeter round the power pins (there aren't many). All the power pins must be powered correctly. 

 

Is this a board you've built yourself? If so, the programming errors may well be guiding you to a build fault - a solder splash or short.

Also make sure you've got the pull-ups in there according to Altera's reference design. Sounds indeed like a physical problem.
