Auto Blog Plugin gone rogue

I went to run a Snapshot and realized the autoblog_log table was 1.5GB! I had to truncate the table before my server space was exhausted. I'm getting 500 errors when trying to access the main "Posts" page. However, I can access some blogs via the Category page, but "Concrete Lifting" and "Concrete Lifting Blog" posts throw a 500. I've disabled the plugin for now. Need help figuring out the problem here.

Thanks,
Mike
