Unable to migrate Win to Mac

I've a new Macbook Pro 512GB/16GB running Yosemite and have installed the trial of Parallels 10.
The Win7/64 machine has antivirus and Firewall disabled.
Both are connected via LAN.
Same version of Parallels and Transporter.
Both have been rebooted.

I get various crashes and on the Win PC n/w connection lost messages (although I think this may be a red herring), but sometimes manage to start the transfer. However, this always fails. I don't appear to have any support from Parallels as I'm on the trial - I'm certainly not gonna pay for it at this rate
Anyone got anything I can try? I've a new ext HDD due today so may try that way, but will be wary that the finished VM will be unreliable.

 

Hi Martinam1,
Please perform Sfc scan on Windows and then follow the steps suggested at http://kb.parallels.com/115007 to check if the issue still persisting.

 

Thanks Ram, I used an ext HDD in the end and now have a running VM. Sfcscan found no issues.
