[Solved] Help importing products from v.1.4 to v.1.3.7

[ihackpro]

Hi,
I started a shop with v.1.4.0.17 and had problems with the invoice numbers, they don't auto increment.
I'm trying to install 1.3.7, I get an error after importing the database : Invalid loadTaxZones() SQL query!
I solved the loadtaxzones importing it from another shop.

everything seems to work, but I can't see the products at the shop or the BO.
I can see the product lines at the database.....

Does anybody know how to fix this? I don't want to start again, I have 600 products....
thanks in advance

SOLVED: Exporting to EXCEL then erasing the columns that didn't match with the 1.3.7 version.
