Please help me guys.

In my case I suspect it is a corrupt preference, because I already took out all the plug ins and also reinstalled DP and the problem remains.

Be sure to check your hard drive with Disk Utility for any errors or problems. Probably not the cause of your problem, but you never know..

And here's "the thing." If you delete the plist and it corrupts again then something is writing a bad plist repeatedly. Likely the app itself, if not a related plugin or driver.

I had a similar problem across all my apps (especially Finale) a few years ago. It was a permissions problem I created myself thru ignorance. In the end I had to rebuild the system from scratch (discs and downloads one by one. I think it took me about 2-3 weeks. I hope I NEVER have to do that again... (famous last words).

Already tried this, in fact was the first step I did.

I already filled a ticket support with Motu, while waiting for response I decided to put back some plug ins I moved from the "Components" plug ins folder, trashed prefs again and now its working!

I force quit the DP several times to see if the problem came back and its working great!

Motu answered back and they ask me to do a few steps in order to track the problem, the thing is that now I can't make it fail! ha ha ha.

Thank you all for your support guys, I really appreciate it.
