Hm.. it seems that it is sufficient. Please start the /Application/Utilities/Terminal and execute in it next three commands (without quotes):
1) "sudo mkdir -p /Users/Shared/Parallels"
2) "sudo launchctl start com.parallels.desktop.launchdaemon"
3) sleep 1 && ps aux | grep prl_disp
then post here the output of the last command and try to start Parallels Desktop again.
PS: You should receive soon reply on support-ticket, if this doesn't help, please reply to the support ticket e-mail and attach to it files /var/log/system.log and /Library/Logs/parallels.log
