Don’t you have to create a writable subdirectory somewhere for the plugin to store files?
I just happened to run across a comment on WP-cache on the ASO forum today. This might help:

wp-cache 2.1.1 was just released this march:

And it works fine with wordpress 2.2.

Ah. I only needed to chmod the config.php so wp-cache could write to it.

Keep in mind I haven’t tested this, it’s just someone else’s suggestion to a related issue, and it might explain the problem you’re having.
If you added the line define(‘WP_CACHE’, true); directly to your wp-config.php, you need to make sure it is at the top, just under the // ** MySQL settings ** //.
I shifted it from the bottom of the wp-config.php to the top and it works now, weird problem.
