Got errors when enabling flexinode

I got the following errors when enabling Flexinode in Drupal 4.7.4. I am using Windows XP Home, MySQL 5.0.27, Apache 2.0.59 and PHP 5.1.6 for my development environment. It seems that the system fails to create those tables because 'TEXT' field cannot have default value. So, can I just remove the default values of those 'TEXT' fields in order to bypass the problem? Will there be any negative effect on the functionality of the module if I do this.
Thank you very much!
