Prl_disp_service crashes after sleep

I was wondering if someone could help me with this problem:

After my mac pro has been asleep for a while (longer than 10 min), Parallels crashes and says:

Unable to connect to Parallels Service.

Make sure that the prl_disp_service process is active and it is not blocked by Firewall. If the problem persists, contact the Parallels support team for assistance.

I just sent a Problem Report. #6533460

I've searched through the forums a bunch of times and have tried most of what I've found, yet nothing has worked besides manually launching the service after it crashes. I did try completely reinstalling, but that didn't change the behavior.


Thanks in advance!
