Can't use InnoDB, my.ini is okay! (2 replies)

Okay, I'm using Windows XP

MySQL Server version: 5.1.46-community

I want to use InnoDB, but when I write "show engines" I get:

Engine Support Comment Transactions XA Savepoints
InnoDB NO Supports transactions, row-level locking, and fore... NULL NULL NULL

I checked the my.ini file and I have commented the skip-innodb line (#skip-innodb)
And I even have default-storage-engine=INNODB

What could be the problem??
