I have a usb wifi adapter by "Glam Hobby", which I can link to if required but basically it's just a rebranded Realtek USB wifi adapter. For over a month I had been using it with the drivers included on the CD it came with, along with a tool called "REALTEK USB Wireless LAN Utility" to manage it - enabling and disabling it, and most importantly easily configuring my adapter's access point mode.
However, a few days ago I installed an updated version of the driver through Windows Update. The second it finished installing, the REALTEK software crashed and it continues to do so as long as the adapter is enabled. If the adapter is disabled, the application doesn't crash right away - but the second it's enabled, it crashes with no error log in the program's folder.
There is, however, the following event logged in Windows:
Faulting application name: RtWLan.exe, version: 700.1689.319.2015, time stamp: 0x550a71ab

I've tried the following things to fix it:
I've done the above with and without restarting, with and without the device plugged in - no matter what I do, I get the event above and the application crashes right away. Windows recognizes and seems to use the device just fine, but the software has refused to work since I installed that patch and continues to fail even after I removed the driver Windows installed.
Is there anything else I can do to try to get this to work again? I realize there are other tools, such as 'Virtual Router', that do the same thing - but Virtual Router just isn't as full featured as Realtek's software and I kind of liked it.
I'm on Windows 8.1 64-bit with all of the latest updates.
