Need help with HDTV program

I have a Kworld atsc110 HDTV tuner card and I don't care for the Beyond TV software that came with it..I've found a program called WatchHDTV 1.85 that is supposed to work with this card, but when I try to run it I get this:

WatchHDTV MFC Application has encountered an error and needs to close.

here's the website: http://mysite.verizon.net/watchhdtv/home/watchhdtv.html

Can someone help me???

I use GB-PVR. Its freeware and seems to work well with my Hauppauge card.
