Exclamation [Q] tablet z sgp311 fastboot driver issue

hello everyone. First time posting here. Im having a terrible time unlocking my bootloader on my tablet following sonys instructions. I get all the way to the part where sony has you download their usb inf replacement file for android sdk. I replace the file, go into fastboot mode on my tablet. the device shows up with the yellow exclamation in device manager but it wont let me update the drivers. I have also attempted to update the drivers through flashtool. nothing seems to work for me and Im at the end of my rope. it just keeps saying that windows cannot find driver software for my device. anyone have any tips or something that can get this working for me? im running android 4.2.2 with firmware 10.3.1.c.0.136 on the sgp311 wifi model. developer mode is enabled as is usb debugging. any help with this would be tremendous.

Are you using Windows 8 or 8.1?

Strange... It might sound silly, but sometimes people forget it: Did you rebooted after installing the drivers from flashtool?

ya, still not updating the drivers. and when its been connected to the computer and blue light is on not getting anything when I list my fastboot devices. Im wondering if I should try and downgrade to an earlier firmware to use the one touch rooter. is that even possible?
