Stereo Pack will not open in Sonar 8

I've had Stereo Pack with Sonar 6 for a few years, and it's a great plugin, especially when I record groups in my small studio.
However, since installing Sonar 8, I cannot get Stereo Pack to open in a track FX bin. Sonar gives a fatal error message and closes. I've Un-installed, re-installed, used both iLok and auth. codes alternately, un-checked the "force to Mono" box in Sonar VST options...everything I can think of. Sonar cannot come up with an answer. I really like this plugin. Any ideas?
Thanks.

Mateusz informed me that Stereo Pack 1.9 does not work with Sonar 8. He advised downloading 1.8, which works fine.
Thanks, Mateusz!

It's a good news...but...where can I get Stereo Pack 1.8? There is only v 1.9 available at the User Area, and (obsolete) 1.6 version which hangs during its instalation : "searching for files....." and nothing else.
What sholuld I do?

Go to download folder for current version and you should see there subfolder older versions.
