Database went nuts after upgrading

Hi guys

I need some help if possible.

My database went nuts after upgrading to 2.0.12, basically I cant add any customers/products/categories.

Heres an exemple.

My last client is the client ID 35. Now if I try to add a new one after filling all the fields I get this error:


[QUOTE]

Database error: Unknown column ‘password_change_timestamp’ in ‘field list’ (1054)

Invalid query: SELECT user_id,user_type,status,user_login,title,firstname,lastname,company,email,phone,fax,url,tax_exempt,lang_code,password_change_timestamp FROM cscart_users WHERE user_id = 44

[/QUOTE]



I get the same error when adding products.



What the hell is going on? any one having this issue?
