wavelab 8 on mac crashes on opening

I am using Wavelab 8 on a mac OS 10.6.8

Wavelab 8 had been working fine for months, in fact 7 is installed and still works fine… but a couple days ago I opened a .DAT file on version 8 and when I closed the program it decided to never open again.
It just crashes on start up.
I have trashed prefs and reinstalled the entire program and still get the same crash.

Anyone have any ideas on why it would be doing this?
I upgraded to 8 as 7 was so buggy… now this, i really feel like i should have just switched it out to something else.

if anyone can help it would be really appreciated.

Thanks
Jason

Are you sure you trashed the right preferences?
They are located there:
/Users/[YourName]/Library/Caches/Steinberg/WaveLab 8

I’m having the same issue. I’ve followed your directory path to find the preferences to trash, however there isn’t a Steinberg folder in my Caches folder. I’ve attempted to spotlight find that folder as well without any luck.
