2.9.2 Mail Plug in Crashes Mail

Installed version 2.9.2. Clicked to install the Apple Mail plug in and now Mail keeps crashing. Not only can I not complete the plug in installation, I cannot get to my mail!

Forgot to include I am using Mac OS 10.7.4

Please see the If the Mail Program Crashes section of the manual. If you can’t get to your mail, you can upload the file to the forum.
