Reinstalling K4PC if latest version crashes

Sorry if this is old news, but I didn't see any recent posts about this....

As detailed in my blog post, K4PC crashed on me today when I tried to launch it. After following another suggestion to download and install an older version (which worked), I then got an email response from Kindle CS with additional steps to uninstall, deregister, and reinstall K4PC with the latest version. This seemed to do the trick. (I suspect the cleaning up of the user app data may have been significant.) If you need to do this, don't forget to back up any non-Amazon content from your "My Kindle Content" folder before deleting it -- or just do what I did and move the whole folder to a back-up location. Here's a direct copy-and-paste of the instructions from Amazon:

Please accept my sincere apologies for the inconvenience caused to you with your Kindle for PC application.

I'm glad to hear that you've tried the basic troubleshooting steps by uninstalling and reinstalling the application, that was the correct action to take. However, as the basic troubleshooting wasn't useful, letís try Real-time troubleshooting steps by uninstalling the Kindle for PC application, and deregister it from your "Manage Your Kindle." Then, reinstall the latest version (1.5) of the Kindle for PC application and re-register the application.

2. Select "All Programs."

6. Confirm everything has been deleted in the -- C:\Users\<USER>\AppData\Local\Amazon\Kindle For PC directory (especially the file).
7. Also confirm everything has been deleted in the -- C:\Users\<USER>\Documents\My Kindle Content
8. Make sure all system updates are performed.
9. Reboot/restart your computer.
