How to reinstall bbm?

I need to reinstall bbm because whenever I press enter to send message, this circle thing will pop up. Hard reset has been done, still the same. I am using 10.6.4.10. I thought it's a hardware issue, but does not happen in any other apps like words, cb, etc

Thanks a bunch

I would think you will need to load a bar file for a different BBM over what you have now since it can't be deleted.

Either load BBM bar file or safer to reload entire OS

Thanks, I will just wait for the update first. If still the same, I will reload the whole os.
