error with user base connection

i installed dolphin 6.0005 with ray adfree


i understood that adfree was not so free

and installed dolphin 6.1 with  free ray

but i suffered some problems with that


when looking to my users as admin
it shows an error database
i cannot view the list of users from control panel


from user aspect every things goes well : all users are present and active

but not at control panel
