Add file to computer in Administrative Data

Question

Hello,

We had an old OCSinventory server on Windows who crashed.

We have the SQL backup so I thought it's better to install a new up to date OCSinventory server on Debian than upload the SQL backup.

It wasn't that easy be it has been done.

Now we face 2 problems.

1. In the old Windows version, we added the corresponding invoice to the computer in the Administrative tab. I remember I added that field so we were able to upload file (invoice) to the server for each computer. Now I can still see the name of that field but there are no files anymore and no possibility to add or download one. I checked and the field type is CHECKBOX. Shouldn't it be FILE ? I cant put back FILE as a field type. How to enable that ?
2. For some computers we lost the date of purchase, it shows 1970-01-01 instead of the real date of purchase and also instead of 01/01/1970.

Do you how I can solve this ?
