Post upgrade forum block shows CCk content

[geniekids]

I upgraded from Drupal 5.1 to 6.6 and while everything else is fine
the forum block (both latest topics and most discussed topics shows
a cck content rather than forum topics.

When i go to admin>content and filter by forum topics - i get the forum topics list alright.
But its the blocks that are listing the wrong content.

I need to mention that i was using in 5.1 the forum taxonomy for categorizing some other cck content also (including the one that is now showing up)

For other CCk content i was using views.
Any idea how to set the forum blocks right.
