Update Error (no replies)

HI!

I got an error during the update. Now the system gets no data from the database.

I get this message in the backend:
INFO Installation[2014-06-04 11:57:00] [0317c] LOAD DATA INFILE failed... Error was: SQLSTATE[28000]: Invalid authorization specification: 1045 Access denied for user 'web1229'@'localhost' (using password: YES)[28000]

INFO Installation[2014-06-04 11:57:00] [0317c] LOAD DATA INFILE failed or not supported, falling back to normal INSERTs... Error was: Try #1: LOAD DATA INFILE : SQLSTATE[28000]: Invalid authorization specification: 1045 Access denied for user 'web1229'@'localhost' (using password: YES)[28000]

What can I do?
