Please help CS4 5.2 Bridge thumbnails

I have installed cs4 with camera raw 5.2 on my p.c. to hopefully deal with the huge raw files from my new camera 5D 2. But I am still unable to view the thumbnail images in Bridge. They open fine into cs4 but I want to view them in Bridge as thumbnail images. Can anyone tell me how to overcome this problem. Hopefully it is just something simple. Thanks.

Look here!!

Thanks . I have read the links very thoroughly but I am now totally confused. When I installed camera raw 5.2 I just followed the prompts without much thought and I have no idea where the original camera raw version is or how to check. I would love to be able to view my thumbnails as photos in bridge but it seems like a complicated process. I hope I can solve it with help from you experts. I would really appreciate any further assistance.

I have tried to do as suggested but no success. I do not fully understand what cache means. Should I totally uninstall 5.2 camera raw and start again. I am reluctant to do this. Or should I just try and uninstall the original camera raw and how would I do that without messing up camera raw altogether. I would have thought when the new version was installed it would over ride the original anyway.

In the meantime I can view my thumbnails in Faststone which is totally free and a very useful storage program.
