[CONVERT] problems with converting Forumotion

[Dafalulu]

So, i've been trying to use Crawler Converter from here:
viewtopic.php?f=65&t=1761395
I've set up the settings file, extracted the cookies with "phpbb3_get_cookie", and when i've tried using the "members_topics_posts_phpBB3" script it said:
Member 1... Warning! Member doesn't exist
Member 2... Warning! Member doesn't exist
Member 3... Warning! Member doesn't exist

and so on.

I've doble-checked, and the theme-version of the Forumotion forum is phpBB3.

What should i do?
