Plesk update problems

[rvdmeer]

It looks like i have a problem with updating to another subversion of plesk. Within the update screen it says:

Base packages of Plesk Aug 24, 2005 Aug 24, 2005 An update is available

Thru console, this is the output when installing the update.

Get Plesk product packages.
Get system update packages.
Start packages installation
Installation done.

When checking for new updates it gives again the same update so installation didnt do anything.
Our current build is: psa 7.5.4-fc3.build75050824.12

If i'm checking the file on the server itself it gives me:

[root@vite base]# cat /usr/local/psa/version
7.5.4 FedoraCore 3 75060321.20

Still it gives: there is an update available...

Could someone please advise?
Thanks in advance!
