Problems with Directory Install

I’ve tried to install directory on a number of sites with the following error when it activates:

Warning: mkdir() [function.mkdir]: Permission denied in /home/vimyhall/public_html/wp-content/plugins/directory/core/data.php on line 247

Warning: copy(/home/vimyhall/public_html/wp-content/mu-plugins/gateway-relay.php) [function.copy]: failed to open stream: No such file or directory in /home/vimyhall/public_html/wp-content/plugins/directory/core/data.php on line 250

Warning: copy(/home/vimyhall/public_html/wp-content/mu-plugins/wpmu-assist.php) [function.copy]: failed to open stream: No such file or directory in /home/vimyhall/public_html/wp-content/plugins/directory/core/data.php on line 251

In the menu the plugin gets labeled as CustomPress and the settings etc have nothing to do with the images and install info on your web site.

Thanks,

Kevin
