Inspiron 15R Touchscreen Gone

So for the first 10-12 days, my Inspiron 15R worked great. Then one day, out of nowhere, the touch screen just stops working. I looked for the driver on my computer, but it has disappeared. I then took to the Dell forums, and found someone with the same problems. I followed the same advice they had been given, but they were ultimately instructed to use the disc that came with the laptop. My computer very specifically did NOT come with a disc, so I don't know what to do. I like the setup of the computer, but it is much more difficult to navigate without the touchscreen. Please help!
