Refresh account details in Directupload plug-in in JOSM

Hey.
I tried to upload a GPS-Track with the Directupload plug-in in JOSM. Unfortunately I entered a wrong password and enabled the option to save the account information. Since I receive the error message “Authorization required”.
Is there a way to reset the account information?

I tried to delete the plugin but it had no success.

Thanks for your answer.

Is it possible that the plugin takes account data from general JOSM settings?

Then try editing at http://josm.openstreetmap.de/wiki/Help/Preferences/Connection

I tried the authentification with OAuth. However it works now!

Thanks for your help!
