Phil,
You will need to use an older version of WildFire to work within SameTime. We modified WildFire from 1.5+ so that preferences are stored as account documents in the users personal address book, rather than a separate config file.
That's why the current version will not work with SameTime stand-alone.
The older versions use the StatusUpdaterConfig.xml file (get a release prior to 1.5)
Hope this helps.
