I don’t want to upload another plugin, but want my stats back!
Here’s what they’re saying on wordpress.com forum — same conversation, but a possible fix without actually activating Jetpack:

I found these instructions below and this worked perfectly for me and my self-hosted blog.
When the problem started 2 days back with the stats, I did not delete WP stats, but deactivated them.
Also when I tried to install JetPack and activate the JetPack stats I got a fatal error.
Following these steps EXACTLY brought back my stats and all the historical data.
If you have been getting this error lately on your www.remarpro.com blog then don’t worry because you are not alone. This error has been a result of a new plugin introduced but the Makers of the WordPress.com Stats called Jetpack. It is very simple to solve this problem, just Follow the Step below
1. Got to Plugins> (Click) Add New
2. Search for the plugin called “Jetpack”
3. Install and activate this Plugin
4. Now either you can got to the plugins menu and under Jetpack click on settings or under the Dashboard DropDown Click on Jetpack
5. Connect your WordPress.com Account and Authorize it
6. Now Don’t Click on the activate Button in the Jetpack Settings as it will give the the Following error “Module could not be activated because it triggered a fatal error. Perhaps there is a conflict with another plugin you have installed?” instead go back to your plugins menu and press Activate under “wordpress.com Stats” (as it Jetpack Automatically Deactivates this plugin)
7. Go back to your dashboard and your stats will there as normal.

I have not tried this, as I really don’t want another plugin, even a non-activated one.
