Hello lurdsammie,
There seems to be a strange table prefix (10_), especielly if you are starting with a fresh installation. If you only have one company, the prefix counter starts with (0_). The file, config_db.php, contains the prefix counter. Check that this is set to 0. Also check that your chart of accounts has a prefix of 0_. Otherwise do a search and replace.
The best thing to do when doing a fresh install is to first create the database, and then run the /install, that way it should be taken care of everything.
