[Plugin: Add Local Avatar] No upload

Hello,

I have the last version of Add Local Avatar and WordPress.
When i upload an avatar, i have this notification:

Warning: move_uploaded_file(/gm.png) [function.move-uploaded-file]: failed to open stream: Permission denied in F:\inetpub\vhosts\freedomcoders.fr\httpdocs\subdomains\geekme\wp-content\plugins\add-local-avatar\avatars.php on line 846

How can I make it running?
