Thanks for logs. But it doesn't help us.
Very very strange situation.
I think that by unknown reasons MAC OS X can not start Parallels Service.
Try to start it manually:
1) start Terminal ( open Terminal by Finder in /Applications/Utilites )
2) type to start:
$ sudo launchctl start com.parallels.desktop.launchdaemon 
and type to show current state: 
$ sudo launchctl list  | grep parallels
$ ls -l /Library/Parallels/Parallels\ Service.app/Contents/MacOS/
3) ( please story all output of command and add it to next post. )
4) after that try to start PD5 again. 
5) If PD5 can't connect again - please make full logs from /var/logs to next post, we should understand and fix it problem.
howto: 
a) type in Terminal 
$ sudo tar czf ~/Desktop/all-logs.tgz  /var/log 
b) attach file all-logs.tgz from Desktop to forum post.
6) and please send Problem Report any case.
Thanks.
