Access denied to tasks?

Hi, I just set up ZohoCRM to test it out and imported a bunch of contacts.

I then went to the home page, and see the module for Open Tasks at the top, but I am told:

"Access denied. If you are the administrator, please update your profile settings. Otherwise contact your administrator to enable the access."

I am the administrator (since I set up the account), and I've searched high and low for profile settings that would allow me to see open tasks, and I can't find it anywhere.

What am I missing?

Thanks
