求助：mldonkey启动不了core

[Tennessee3Waltz]

启动mldonkey时应该是：
lxy@ubuntu:~$ /usr/bin/mlnet
2010/05/10 10:07:10 [cO] Starting MLDonkey 3.0.0 ...
2010/05/10 10:07:10 [cO] Language EN, locale UTF-8, ulimit for open files 1024

可是我启动mlnet时是：
lxy@ubuntu:~$ /usr/bin/mlnet
2010/05/10 10:07:10 [cO] Starting MLDonkey 3.0.0 ...
2010/05/10 10:07:10 [cO] Language EN, locale UTF-8, ulimit for open files 1024

即，没有最后一句核心已启动。同时http://localhost:4080/也就打不开了。
我昨天晚上刚安装了，命名都下了好几个视频了的。但昨晚关机前http://localhost:4080/就已经打不开了。我不知道为什么。我想来想去，我只改动了下sudo chown lxy ./mldonkey/incoming/files，本来是root的，我改成lxy，即我自己。不知道有没有影响。实在搞不明白怎么就打不开web界面了。大神们，帮帮忙阿。
