ERROR: Can't add to black list product package psa

[andized]

Hello,

i am running Suse Linux 10.0 and recently installed Apache/2.2.3 and PHP 5.2.0RC5.
When i try to reinstall Plesk 8.0/8.0.1 with the auto-installer (psa_installer_v3.0.2_build060704.16_os_SuSE_10.0_i386) the following error occurs:

• 
  Download file build-8.0.1-suse10.0-i386.hdr.gz: 10%..20%..30%..40%..50%..61%..70%..80%..90%..100% done

  Resolve components
  ERROR: Can't add to black list product package psa
  ERROR: Installation failed

i dont know what this error means and why the packacke psa has to be added to a blacklist.
is there any way to bypass this problem?
