With this sort of error simply re-uploading will not work.
To fix this setup scripts must be triggered. This can be done only by re-initializing the install process with Magento cache DISABLED.
1. Disable any Magento cache.
2. Login to your database;
3. Execute:
DELETE from `core_resources` WHERE code LIKE 'usimple%_setup';
4. Enable cache.
