every time disappear links or data of products.

[Voila]

I have a site already completed, but I was wrong: I put the products grouped instead of configurable products
The products grouped can not create associations with other products grouped so I have to export the db add the associated product and finally reload the db.
But every time they disappear links or data of other products.
who can help me?

You will need to create new Configurable products then associate your simple products with that. There is no automatic way to convert from a grouped to a configurable.
