Kunena to SMF - boards/child´s boards problem

[tajo]

Hi,
I want to convert my Kunena 1.5.x forum to SMF 2.0 RC3. I used convertor from this page http://download.simplemachines.org/?converters;software=kunena . Transformation was succesfull, but

1) the structure of categories/boards and child´s boards is very chaotic. Actually, there are no child´s boards after transformation.
2) converter escaped all " and ', after transformation there are \ everywhere
3) avatars doesn´t function (but it is not big deal)

Could you help me, please?

Thanks a lot.
Best regard,

tajo
