Try clearing your Java cache and trying again - this will download a new version of the Designer.

Al’s suggestion is the right place to start. Also clear your IE6 cache.

We are seeing a few reports of this error coming in, it seems to be a problem isolated to IE6’s faulty caching mechanism, where it removes the JNLP from the cache before invoking javaws.exe for some reason we haven’t identified yet.
