Nikon D90 thumbnails & Bridge CS4

[Woofa]

hey all recently got a Nikon D90, love this camera.
when i import my RAW files and go to check them out in Bridge CS4 all i get are icons, not thumbnails, no matter what view mode i use.
i have the latest ACR and im pretty sure its in the right place and even did an adobe update.
i can see them fine within Lightroom 2.1 any ideas on this?

In Bridge, purge the cache for the folder that contains the D90 files.
