Migrator imports only K2 categories and not K2 items

Hello, I have installed EasyBlog to my K2 based website and I tried to migrate the K2 items. I had to do this one category at a time. On the right side I could see the progress, only something didn't seem right. The messages were like this:

Migrated K2 item: 123 into EasyBlog with blog id: 

And no ID was assigned. When I went to see what was migrated, I could see the categories but no entries whatsoever. I also checked the database and it is empty (except the single default post in Uncategorized)
