Unable to register the migrated virtual machine

I bought the Parallels Desktop 8 Switch to Mac Edition and tried to transfer my Windows from PC to my MacBook Pro With Retina Display via Parallels USB Cable, but it didn't succeed. When the process was about at midpoint, I got the following error:

So with the result from migration I couldn't do much so I migrated it again, but the results were the same. What should I do now?

 

Please locate the virtual machine file and open it with Parallels Desktop. If the problem persist, contact the Parallels support team for assistance.
