Issue with Adobe Bridge and Pixinsight

[Tennyson]

Hello, I expect there is a real simple fix but I cannot find it.
I have downloaded Pixinsight and now when I use Adobe Bridge, Pixinsight appears to be the new previewer hence the thumbnails appear blank. If you double click the images they will open in Camera Raw ok. So I guess there's a setting in Bridge that Pixinsight has over ridden....Would that be correct?

Could one of clever people advise what I need to do to fix this? 

Cheers

Right click on an image icon and select "open with". Below the options for programmes to use there is another menu option "choose another app". Select that and a list of programmes will appear together with button "always use this app to open.....".
