I see you posted while I was formulating a response. Yes you must use a fully new
vb with no special groups or if want you can create those
vb groups with the same id number as the ones in photopost and just remove the code in the import script that renumbers the user's usergroup and let the import script import that groupid in its normal format. Remember the script I wrote is designed to import into a clean
vb format which has no custom usergroups so this is your issue.
