Problem with the database

[wottshop.nl]

I have a big problem, I would love it if anyone have has a solution.

A while ago I upbraided to 1.4, But I had so much problems I'd wanted to downgrade.

So I replaced the map on the server, But forgot to do downgrade the database.

In the meantime I found some solutions of the problems I had, So I thought if i'd just replace the map again it all would be fine.

So I replaced the map of the webshop again, Everything went well, untill I had to gave the permissions in the install folder.
Nothing worked, So the guy from the webhoster and I tried to upload a backup of the database, but there was something wrong in that backup, So everything is still there but in a way prestashop can't read it.



It would be a disaster if I have to customize the whole shop again, So any help would very much be appreciated.
