I tested this card, afraid to say you've bought a lemon, that card is the worst I ever tested, it lost connection to channels individually, it missed steps on a monumental scale and caused runaways.
It may seem to work now but I guarantee it will crash your machine.
I suspect you've bought it off eBay from China so you'll be lucky to get a refund, but your best bet is try to or do what I did and put it straight in the bin. The company that built that card built only that card sold a load and closed up shop because they don't work. Infact they are downright dangerous.
Sorry mate
