Answer 1

You have to modify few line in (/system/libraries/Upload.php)
from:
$this->file_type = #mime_content_type($file['tmp_name']);
return;
to this:
$this->file_type = #mime_content_type($file['tmp_name']);
if (strlen($this->file_type) > 0) return;

Answer 2

Check the config/mimes.php have the correct value for "csv"
In $mimes array,find the 'csv' and check the following.
'csv' => array('text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel'),
If not, add this into it.
