Partial import

Hi,
I’ve purcased the premium version and I’m trying to import a relatively large joomla db, working on my local machine (running MAMP).
I’ve tried several times to rerun the import, by i get only the half of the posts (more or less).
Tried to use more RAM on php, but the result is the same.
Is there something more i can do?

Thank you!
