When I open CS4, it crashes with out an error message box coming up. The second attempt, it crashes with the message box saying, Error 150:30, Licensing for this product has stopped working. I then have to go to the hard drive > library > application support > Flexnet publisher and delete it. I then can open up CS4 and it stays open. I have had to do this procedure for many months. I am using Mac OS.6.8. Is there a way of preventing CS4 from crashing without having to go through this procedure?
If it crashes, you would get a crash report dialog.
It sounds like you either have a bad install, or a bad license.
