Have you upgraded to the latest version 2.2.2.20?   Should be at Download.com now,  v2.3.x.x is being released later this week as a beta.  DAZ has changed the way future releases will be handle,  a public beta will be posted in the official DAZ Studio forum, when they feel they have worked out the bugs in that beta it will then be posted to Download.com as the current stable release.
