Friends, help to understand. The mistake is constantly given out at installation

Warning: File already exists

in/usr/home/web/public_html/pagetool/src/setup/include/setup_upload..inc on line 29

Warning: fopen (" ftp://... @www.5kopeek.ru/pt_config.inc ", "wb") - File exists in/usr/home/web/public_html/pagetool/src/setup/include/setup_upload.inc on line 29

It seems as if you had an error with pt_config.inc

At transition to the second step, the line is deduced and asks to specify let to pt_config... What there it is necessary to enter?
