Calendar Version 2 - Can't add new records

Hello,

I installed the latest version of the calendar (Version 2),

but when I try to add a new record into the calendar it gives me a blank page.
I check for the page permission and it seems fine, I am using the admin log-on,
Does anyone knows if there is anything else that needs to be done, do I have to do anything

with the tables or change the code some where?.
I am not adding my own table, I am using the existing tables.
Sincerely,
