MAMP MySQL不会启动

我完全卸载了MAMP，从MAMP网站上下载了MAMP 2的新版本，做了一个干净的安装。 但是，当我尝试启动MySQL，我得到以下错误日志

111120 21:37:49 mysqld_safe Starting mysqld daemon with databases from /Applications/MAMP/db/mysql 111120 21:37:50 [Warning] You have forced lower_case_table_names to 0 through a command-line option, even though your file system '/Applications/MAMP/db/mysql/' is case insensitive. This means that you can corrupt a MyISAM table by accessing it with different cases. You should consider changing lower_case_table_names to 1 or 2 111120 21:37:50 [Note] Plugin 'FEDERATED' is disabled. 111120 21:37:50 InnoDB: The InnoDB memory heap is disabled 111120 21:37:50 InnoDB: Mutexes and rw_locks use GCC atomic builtins 111120 21:37:50 InnoDB: Compressed tables use zlib 1.2.3 111120 21:37:50 InnoDB: Initializing buffer pool, size = 128.0M 111120 21:37:50 InnoDB: Completed initialization of buffer pool 111120 21:37:50 InnoDB: highest supported file format is Barracuda. 111120 21:37:50 InnoDB: Waiting for the background threads to start 111120 21:37:51 InnoDB: 1.1.5 started; log sequence number 1595675 111120 21:37:51 [ERROR] /Applications/MAMP/Library/bin/mysqld: unknown option '--skip-locking' 111120 21:37:51 [ERROR] Aborting 111120 21:37:51 InnoDB: Starting shutdown... 111120 21:37:51 InnoDB: Shutdown completed; log sequence number 1595675 111120 21:37:51 [Note] /Applications/MAMP/Library/bin/mysqld: Shutdown complete 111120 21:37:51 mysqld_safe mysqld from pid file /Applications/MAMP/tmp/mysql/mysql.pid ended 

我不知道为什么会这样。 我search了一下，确保没有MySQL的实例正在运行。 似乎没有任何帮助。
