trouble with install

I created a site on my localhost and moved it to a server via ftp. Although it appears that everything transferred correctly the theme is not working. I am getting this error:


Warning: include_once(/home/a4437977/public_html/wp-content/themes/atahualpa/functions/bfa_theme_options.php) [function.include-once]: failed to open stream: No such file or directory in /home/a4437977/public_html/wp-content/themes/atahualpa/functions.php on line 14

(same error for lines 16 and 17)

Also, when this happens I am not able to use any themes. I have to go back to my file manager and delete the atahualpa folder completely in order for any theme to work.

I have contacted the host who is trying to help me but the problem still persists.

Even though I know I will lose all my existing work I wanted to just install the theme again on my site and start from scratch. When I try, however, the theme will not install. I have tried to install it by uploading it from my computer and also by searching themes and uploading it from there. Neither way has been successful for me.

Can you help?
Thanks!
