Hola todos, me gustaria saber si alguien puede explicarme o darme algun link dnd se explique como importar mi foro SMF, Simple Forum Machines a mi nuevo foro VBulletin, paso a paso o algo claro q me diga q debo bajar e instalar. baje el impex y hice todo mas o menos como crei y me da este error cuando empiezo el primer paso:

ImpEx build version : 1.57

Using includes/config.php for target config.

Altering tables

ImpEx will now Alter the tables in the vB database to include import id numbers.This is needed during the import process for maintaining refrences between the tables during an import.If you have large tables (i.e. lots of posts) this can take some time.They will also be left after the import if you need to link back to the origional vB userid.

There seems to have been a problem with the database.
