My original suggestion still stands. The ImpEx script does support many source systems. Most pf these systems are not converted from on a regular basis. Result of this can be that if you use a newer version of the source system then the latest customer converting from that system, there need to be done some updates to our import script. By doing this yourself and if needed contacting our support desk, you will get direct access to the best professionals on vBulletin you can get, and if any updates to the import script are needed to make it work with a newer version of the source system, even the developer of the script will step in and update it for the newer versions. And best of all: this us free, you already pay for support when you purchase a license.

Did you open any sales ticket regarding these questions, or did you post on vB.com?
