It's unusual. I think you should contact DDU about the driver and reinstall it, though I'm not sure it would fix anything. It could also be tough to locate the right driver (I'll check it). The decision is yours—what works for others might not work for you. Edit: Hmm, are you using a Dell PC? The driver I'm looking for is specifically for the HD 7470 from Dell.
