I have already reinstalled it but it did not solve the problem....this is the message i get after trying to start it up.....Parallels Desktop is unable to operate properly since it cannot communicate with one of its drivers. Try to restart the application to overcome this issue. If restart doesn't help, re-install Parallels Desktop. Note that Parallels drivers require a short time to be properly started and initialized. So you may need to wait a minute before trying to launch the application.
