upload attachment file to form

Hello

I wish to upload a file so it can be attached to the mail message sent from the contact form.

I followed the instructions: http://contactform7.com/file-uploading-and-attachment/

The file is never attached. The only things that gets in the mail message is its name.

I have modified uploads and wpcf7_uploads folders both to 777
Although, the file does not get uploaded to the server.

What I did notice is that every time a file is uploaded, the system or the script for uploading recreates an htaccess file with Deny from all.
Yes it sounds wild!!!
Any ideas as for how to resolve this??
I tried removing htaccess, commenting the line, renaming the file…
But every upload I try the (I guess) folder gets recreated with the new htaccess–Deny from all….

Thank you
