Neo Soul keys trial won't work, and killed halion sonic se

I’m using Cubase 6, win7 64bit.
During the last 50% off day, I have installed the Neo Soul Keys TRIAL version.
It does not work - I get the “Some audio files are missing” message.
And not only that- I get the same message for the Halion Sonic SE too!
Now, I can’t load projects with sounds I used from Halion Sonic, I can’t try the Neo Soul Keys,
AND I missed the 50% off day!

Any Idea what happened?
