[add via email] Modul will not be installed

Hi,

someone here has tell me about this modul:

http://codex.gallery2.org/Gallery2:Modules:addviaemail

But the installation of it will never be completed. The status bar will stop and the installation also.
The modul looks installed, if i klick the "back" button of the brwoser, but i get errors, when i want to run it.
I think, that it is not "registered" correctly, because it is not shwon in some boxes, whre the author tells in his "installation guide".

i use gallery2 in a "multiple Install" mode.

If i run the script, to poll the mailbox, i get "accesse denied" errors, of a nonexistent module.
Can someone help me ?

Jan

ps. sory for my bad english ;)
