Help. I accidentally trashed my slackpkg updates.

I have totally corrupted my update files, and slackware no longer updates anything. I tried to "fix" the update problem. I probably really fouled up by deleting all files in the /var/log/packages, /var/log/remove_packages, and /var/log/removed_scripts. I then did a slackpkg update to reinstall all files, but this failed to completely repair the problem. My new /var/log/packages file is still missing many installed or upgraded files.
Any chance to fix this, or should I bite the bullet and reinstall?
