Since you are running Asterisk, it would make sense to use a Linux based
FTP server. At least then you would have decent logging (turn on verbose
logging) which you can post the output of. I would also suggest sniffing
the FTP attempt with ethereal or tcpdump to get more info on it.

In any case, you are going to have to get more details:
When  you say "session", is it actually logging in correctly? Finding
the files it is looking for? Or is it just a connection attempt?

My guess is that it either is not logging in correctly or is not finding
the files it wants, or it IS finding a file but doesn't like it.
Possibly one or more of the files is corrupt.
