I used my software and cable (Romanian) a few days back with no issues. Ive scanned dozens of BMW's with it, and its always worked perfectly, although initially I had to get the Romanian guy to help me install everything remotely, once he did, it worked perfect!
as others stated, you have to turn off your antivirus and firewall, and make sure your battery (computer AND car battery) are charged up fully! I usually put my X5 on the battery charger while I work on the computer.

thinking of changing to a Foxwell NT-510 in the near future though.
since most of my laptops are mac, and my Microsoft based stuff is all windows 10.
