Well, I tried a bunch of stuff, and finally got it to work...FOR NOW. Here's a few things I tried that might have helped...or made things more difficult. When I did the last step it finally started working.
I first tried doing a bunch of stuff through control panel, to check out the device, but it mostly froze.
I went thru HP Recovery Manager, and first tried reinstalling the driver. It didn't work, but may have caused something.
Then, thru the same place, I actually chose the option to System Restore. This may have caused it to start noticing a missing driver.
Right after I did this, I went to this official link, and downloaded the driver online and installed it. Now it works.

After I did this, it works, but some wierd stuff did come up, but I couldn't really choose anything. Hope it works for now on, and I hope this helps others!
