[Qgis-developer] OSGeo4W installer: lost plugins, configuration, not printers

[Denis Rouzaud]

Hi,

I just updated qgis-dev using OSGeo4W installer. I had the bad surprise 
that all plugins and the configuration (toolbars, etc) were lost. Also, 
I don't have access to the printers when trying to print.

Anyone knows what could have happened?

Is there a way to restore the config?

PS: installation was done on an admin account, while QGIS is used in 
another user account.

Cheers,

Denis
