My set is a IMAC with Intel Core 2 Duo (2.4 Ghz) with 3 Go RAM
My graphic card is an ATI Radeon HD 2400 Bus

I bought the license for APPRENTICE HD but each time I want to run it, Houdini and License Administrator crash shortly after they are started. There is no error message. I can see within a few second the application launch main page.
Please would you mind help me.
Cheers.
