[Plugin: Register Plus] not working on WPMU

logo is not saving – throwing error on login page:

Warning: getimagesize(/home/myhome/public_html/wp-content/uploads/logo250x78.gif) [function.getimagesize]: failed to open stream: No such file or directory in /home/myhome/public_html/wp-content/plugins/register-plus/register-plus.php on line 1531

My file upload dir for WPMU is “wp-content/blogs.dir/1/files”, not “wp-content/uploads/”, which is probably why this plugin is not working on WPMU.

BTW, the plugin homepage link win WP admin goes to 404 not found.
