Acer V3-571G Bluetooth not working on Windows 8.1

Hi,

I've upgraded my laptop from Windows 7 to Windows 8 using the upgrade assistant. Everything was working flawlessly up until I upgraded to Windows 8.1 and that's when trouble struck. For some reason, my bluetooth adaptor (Broadcom) is no longer recognized by the OS, as in it believes such an adaptor does not even exist.

I'm on the latest BIOS available for the laptop which is 1.13 and I have all the latest drivers from the Acer drivers page. The bluetooth adaptor is the only thing not fucntioning. The driver setup just quits everytime after failing to recognize the adaptor's prescence. I don't want to revert back to Windows 8 because its much less stable than 8.1. Any idea why its not recognized? There are updated v2 BIOS files but they're incompatible with my motherboard. Does Acer have any workaround or can their technicians release another BIOS file to rectify this issue if the motherboard is the issue?
