hi ignacio ..
oh oh oh.. Sorry ..
(I forgot to update this post)
Due to no reply.. until now.. I made a copy of the database... deleted all files through FTP, installed once again, loaded in copy of database.. and wupti.. it worked.. and emails where send... So I do not know the errors... Talked to my host, and we ran through the log files.. no lock.. so I have no clue what went wrong.. but it is working now...
Thanks for your reply...
