Hi @none_none3,

It seems the module Dhl/Versenden is trying to install itself and create the table aw4a_dhl_versenden_label_status but that table already exists.

That's what the error means.

You should find a way to avoid that step, or delete the table (make a backup before) if you didn't use it yet. 

Or maybe you will need a little bit of help from qualified support to sole this issue. Isn't so hard but tricky.

Exactly.

It was an update which somebody else started which got stuck writing the table in the mysql database because it was already there.

I stopped the actualization process, removed maintenance.flag and everythings working like a charme.

Next time i know, i just have to delete the given table in database in order to continue updating.
