Reinstall Plesk 9.5.2? login.php3 missing

[trec]

I had a hacker attack on my server.
The attacker deleted all the log folders on server and removed some binaries and the login.php3
/usr/local/psa/admin/htdocs/login.php3 <-- is missing

So I currently get a 404 error when I try to login to Plesk.
The server is working fine, the database is intact with all the information, so I need to recover Plesk.

Can I re-install Plesk over the same instalation and recover the system without loosing data?
what command should I use?
or may be I could use the autoinstaller command line and select to upgrade to a newer version as 9.5.4, will it work?

current version:
9.5.2 RedHat el5 95100504.14

Thanks

login.php3 file is a part of psa package. For example:

# rpm -qf /usr/local/psa/admin/htdocs/login.php3
psa-9.5.4-cos5.build95101209.05

You can try to install package http://64.131.90.31/PSA_9.5.2/dist-...ase/psa-9.5.2-rhel5.build95100504.14.i586.rpm with force and nodeps options for rpm command.
