usb serial cables are very cheep on ebay about $2 that should be able to fix it, if you want to go that way
another way is to get a solder sucker to clear out the holes (depends on how good you are at soldering)
and the last way is just solder some short wires to the solder points (you can do this on the backside as it's easier) and shove the wires into the jtag connector
