besides following rabideau's advice, XOOPS comes with an md5 script that helps you troubleshoot things like this:
from the XOOPS 2.016 readme:

Files integrity check
The full XOOPS package is now released with a script able to check if all the system files were correctly uploaded to the server. To use it, follow these instructions:
1. Upload the xoops_md5.php and xoops.md5 files located in the XOOPS package root to your XOOPS server folder (putting them next to mainfile.php).
2. Execute xoops_md5.php with your browser
3. If necessary, re-upload the missing or corrupted system files
4. Remove xoops_md5.php and xoops.md5 from your server
