What version of Stylus RMX are you using?
Have you downloaded the latest version?
http://www.spectrasonics.net/updates/index.php

Is this the first time you have tried to install Stylus?

Run the Apple disk utility in apps/utilities/ and repair permissions/authorizations whatever they are named in English
Then, use OnyX (it's free) to run the BSD maintenance scripts and a few other things to clean everything around.
And try again.

If it doesn't work, rerun Apple dik utilities and then trash everything stylus related and try again.

Save if someone has an idea, after that, I'd call/email Spectrasonics.

The reason why I ask which version you have is that there were some people having problems authorising 1.2 of the Audio Units version.
1.2.1 fixes this problem.

You are also aware that version 1.2 requires a new authorization number to previous versions of the plug-in.
So you will need to obtain a new authorisation code from the spectrasonics website if you had a previous authorisation number for an older version of the plug-in.

Also instead of typing the number why not just copy and paste?
