The biggest issue of using dts for this forum are the many relationships, You need to know what table to improt first. If you import the tblAuthor but do not yet have the tblGroups it will confilct. An order as follows that has always worked for me:
tblBanList, tblConfigurations,tblDateTimeFormat,tblSmut,tblPoll, tblPollChoice,tblGroup,tblAuthor, tblEmailNotify,tblPMMessage, tblBuddyList, tblCategory,tblForum, tblPermissions, tblTopic, tblThread and tblGuestname.
Now this list is sure not static but like I said it worked for me and you will not get any PK errors.
