You can use the button in the top right corner of the Jetpack menu to disconnect Jetpack from WordPress.com:

To solve your issue, I would recommend that you delete the Jetpack plugin files, and reinstall the plugin manually by following the instructions here:

It might solve the issue if some files were missing from the Jetpack plugin you installed earlier.

Is that screen shot taken from the dashboard of your/a blog? That’s the issue. Once Jetpack is installed, I don’t have access to my dashboard. It just becomes a totally blank white page until I go and delete it through an FTP program. o_O
The screenshot is from my blog, yes. If you get errors when installing the plugin, try installing it manually, as I suggested earlier.
If that doesn’t help, I would suggest that you check your server error logs to find out more about the blank screens, and why they appear.

Yeah, I tried installing it manually and I get the same thing. Once I try to access the dashboard, I get a blank white screen. I don’t know much about the back end of things. How do I check the error logs, or what can I tell my web master to look for?
Thank you for all your help by the way. ^_^
If you do not know how to access your error logs, your hosting provider should be able to help!
Once you have access to the logs, look for errors around the times where you tried to activate Jetpack, and send us the results via email so we can have a look:
