Serious bug in the user/admin settings?

[juppjupp]

I just noticed that my user now has been degraded to "shopper" after the
upgrade to VM 1.1 (from VM 1.0.15), and when I try to change the user to
"store admin", I get "no access to module" or something like that when I try to access "storeadmin" stuff..

Also, I cannot edit (it is missing) "users" in the front end admin even if set to be able to admin if not portal user.

Is this a bug, or am I doing something wrong? 

Using J 1.0.15.
