"Optimization library not found. Please reinstall the plugn"

I have been able to make HSO work in Windows 7 and Cubase 7 but every time I open one of the projects with HSO applied to a few tracks, HSO nags me that “Optimization library not found. Please reinstall the plugin”.

What is wrong with my installation? I have reinstalled just five minutes ago but it still gives an error. However the strange thing is that HSO seems to work but I don’t trust that it works perfectly because of the error.

Has anyone got any similar experience of HSO? What am I doing wrong and what is “optimization library”? I have tried to include all the VST Plugin paths and they are all there but no - it gives an error and I hate it.

Thanks in advance.
