fopen, fread, fclose erros #2

Hey buddy,

I got the exact same problems as another guy a year ago.

<b>Warning</b>:  fopen(/www/htdocs/w01292e4/projekte/my-project/wp-content/plugins/affiliate-wp/affiliate-wp.php): failed to open stream: No such file or directory in <b>/www/htdocs/w01292e4/projekte/my-project/wp-includes/functions.php</b> on line <b>4198</b><br />
<br />
<b>Warning</b>:  fread() expects parameter 1 to be resource, boolean given in <b>/www/htdocs/w01292e4/projekte/my-project/wp-includes/functions.php</b> on line <b>4201</b><br />
<br />
<b>Warning</b>:  fclose() expects parameter 1 to be resource, boolean given in <b>/www/htdocs/w01292e4/projekte/my-project/wp-includes/functions.php</b> on line <b>4204</b><br />

Any idea how to fix this?
