Unable to activate Parallels Desktop 7

Hi all I am using Parallels Desktop 7 trail version and I am not able to activate it.

I have tried Uninstall and re-install Parallels Desktop no luck then I uninstalled Parallels Desktop using sudo commands and restarted Mac and installed it back no luck and also I removed licenses.xml file and uninstall and re-install no luck.

I performed Repair Disk Permissions many times and I restarted Mac 100 times and I created another account on Mac then I tried the same on it but still I am unable to activate Parallels Desktop.

Can anybody know the fix for this issue?
