Hi,

I have a live openerp7 environment. I do my developement in local pc restoring the live dB and the running local version. And this model has worked for me fine for months.

After resintalling the OS on my laptop whenever I try to login to openerp I am getting the following error:

The model "sale.order" specifies an unexisting parent class "sale.order" 
You may need to add a dependency on the parent class' module.

Note that openerp version & custome modules are identical in both live & test environment.

Any Ideas?
