Problem: When trying to start the pcMobile service it does not start on the first attempt. On the second or third attempt it starts.
Some anti virus programs like McAfee takes very long time for scanning the program files.
Try to disable your anti virus program while starting the service.
If that solves the problem, try to configure your anti virus program and exclude the pcMobile folder from being scanned and then enable the anti virus program again.
