I just installed MySQL 5.5.13 using the Windows installer on my Windows 7 box. The Windows mysql service won't start. Taking some advice from other posts, I ran mysqld --console from the bin directory. Here's what I got:

C:\Dev\Tools\mysql\MySQL_Server_5.5\bin>mysqld --console

There are no files in the data directory, just mysql and performance_schema subdirectories. I have write privileges to the directory. Can someone help?
