You'll need to clear out the older version of IDV from the cache. You can do this by starting the Web Start cache manager: http://www.unidata.ucar.edu/software/idv/webstart/IDV/player.jnlp Find the IDV in the list of Applications. Also, click on the dropdown next to Show: and select Resources. From the that list, delete any instances of idvbase.jnlp.
