I'm testing the newest version on a near vanilla install of ZC 1.5.5f, I said "near", because what I've already installed is a custom template, that's it nothing else and now dbio 1.4.1

I had dbio running for a long time in my live 1.5.3 store, and without problems, well the new version is not working with my export files, I have files with 19,000 products that were handled fast and efficiently by the old dbio 1.1 but this new version gets stuck, as suggested I manually added the "v_products_id" column, and now the 10Mb file that works fine in the old ZC seems to get stuck at 33%, I checked the logs and nothing is there!!! So please tell me how to fix this as I am in the process of migrating my old 1.5.3 store into a new 1.5.5f
