JUser: :_load: Unable to load user with id: 42

[aeeeaom]

I's using VM 2.0.14, Joomla 2.5.8 and PHP 5.3.2.  When I try to change the parameters of the store I get the following error message.

"JUser: :_load: Unable to load user with id: 42"
I have not deleted any user in my database.

In mysql database:
