Serious problem of databases during the upgrade to V1.1

[amyal]

Hi there. My techie budd have encounter theses problems when trying to upgrade the new version of ps databases from V1.0 to V 1.1 :

Table ps_access : in the new version, the field 'id_access' doesn't exist anymore.(Unknown column 'id_access' in 'field list')

Table ps_connexions : here, two fields'name have changed ('id_customer' seems to be replace by 'id_guest' and 'date' par 'date_add') because here is what i see :
old : id_connections, id_customer, ip_address, date
new: id_connections, id_guest, id_page, ip_adress, date_add, http_referer

table ps_country :
new field deleted, the message was
Unknown column 'deleted' in 'field list'

#1146 - Table 'ps_newsletter' doesn't exist

table `ps_product_lang`
#1054 - Unknown column 'availability' in 'field list'

After suppress theses 5 tables, installation starts again, but it lack some menus on the home page and there is a message "Tentative de piratage".

Do somebody encounter such problems ?

Thanks for u help guys !
