[Plugin: More Fields] No fields added, just outputs "a:"

WP-version 3.0.1
More-Fields 2.0.3

1. Registered Event custom post-type in functions.php
2. Installed more-fields to add datepickers and location meta to the custom post-type. Creation of these metaboxes in the setup seems to work fine.
3. While adding a new post of the custom post-type, all that the field outputs is “a:”. Tried reinstalling/disabling all plugins. Nothing seems to get it working as desired.

Would love a functioning version of this plugin, especially since it can specifically target custom post-types! ??
