Cubase 7.5 and HALion Sonic SE Content Downloads - SOLUTION

Luis or other forum members

I recently purchased Cubase 7 and updated to 7.06. I was within the grace period and have updated my usb licenser .
I have downloaded the ISO image for cubase 7.5 and for the Halion Sonic SE content onto DVDs.

During installation of EDM Midi Loops, Groove Agent SE and also Halion Sonic SE2 state "string reading from file…D/… verify that the file exists (with and option to retry or cancel). I tried retry on each of these with no luck.

There is then an error messages that the installation of each of EDM Midi loops, Groove Agent SE and Halion Sonic SE2 failed - fatal error during installation.

Halion Sonic now brings up error windows stating that content is not there even if I go back to Cubase 7.06.

Please could you suggest a solution to this.

Many thanks.
Steve
