Update plesk 10.0.1 to 10.1.1

[fuleranb]

hello,

when I want to update the plesk version 10.0.1 to version 10.1.1, I get an error:

Installing the package hspc-plugin-pp-bt-dtaus-3.3.3-11011213.i386
Can't call method "prepare" on unblessed reference at /usr/lib/perl5/site_perl/5.8.8/HSPC/WebDB.pm line 273.
erreur: %post(hspc-plugin-pp-bt-dtaus-3.3.3-11011213.i386) scriptlet failed, exit status 2

ERROR: An error occurred during installation of packages.
Attention! Your software might be inoperable.
Please, contact product technical support.

Autoinstaller now says I am in 10.1.1 but the update was not performed properly.

What can I do?

Thank you,

Benoit
