Major problems [SOLVED]

[Mizzen]

Hello.

I started having issues tonight after some firmware update on the controllers.
At first i couldn't connect both of the controllers, only one, as it was saying i already have 2 controllers paired so the other one had the led green and the other one blue.
So i tried going to steamapps\common\SteamVR\tools\lighthouse\bin\win32, opening the lighthouse console and typing in unpairall, then trying to pair them again. This did not solve my problem, as it was still saying that i have 2 controllers paired. When i started having these problems (after updating controller firmware) SteamVR also told me i have to update the headset firmware to continue, so i did. It took a short while and said that the update had failed. I tried to update again and it took about a second to tell me that it had updated succesfully and i clicked finish, which restarted SteamVR. Right after it was running again it asked me to update headset firmware AGAIN, so i did and restarted SteamVR again. It just told me to update headset firmware on each startup like a neverending cycle. I've tried to fix the controller issue by resetting the controller, reinstalling all USB drivers, reinstalling SteamVR and completely deleting and reinstalling everything related to SteamVR and HTC Vive. None have worked.
After reinstalling Vive however, i cannot open any application, as it gives the following error: VRApplicationError_UnknownApplication. Not only that but now SteamVR will detect nothing. Not the headset, controllers or base stations(they still show a green light). When the link box HDMI and USB cables are connected to the back of my PC SteamVR will STILL tell me to update headset firmware, without even detecting it!

TL;DR:
-Can only pair one controller
-Endlessly asking for headset firmware update
-Unknown Application error
-SteamVR won't detect anything

The system worked earlier today, as i played it with my friend but right after i updated some controller firmware nothing works. I'm not sure if the firmware update is the reason behind these problems but i can't think of anything else.

Thanks in advance.

Edit: Apparently everythign works normally when i run Steam as administrator.
