Help sync with yahoo calendar & contacts

[asres]

The last time I remember, my yahoo calendar and contacts were in sync with my galaxy nexus phone, but now all those entries are gone in my phone. I didn't do anything except that I proceeded with the ICS update to 4.0.2 the other day when the notification appeared.
I tried to manually sync (Settings > Accounts & Sync) several times but to no avail.

Do you guys encounter this problem.. and have you managed to fix it?

Appreciate very much your inputs!

Hello folks, did you have to configure anything on your phone to synch any changes made on your phone with Yahoo? If so what did you have to do? And, were you successful for both contacts and calendar?
Thanks for your help!
