There was an error in my converted phpbb sql file, the error clearly pointed me to the right direction. So all I did was download the phpbb database, then I traced the error down to the line that was being pointed out, I deleted what I thought could be causing it, saved it and exported it back to the database.

As soon as I ran the converter script, it worked like a charm.

Are you having any problem? It didn’t take me more than 30mins to do all the conversions. I was initially on SMF, converted that to Phpbb, before finally converting to bbpress.
