I downloaded the Skype app a few months ago, but then it randomly stopped working and when i checked the Windows store it refused to install any apps or update them and the error number "Code: 0x80073D0A" when nothing will download or update. I've reset the store via command prompt but to no avail and i've not modified the store etc in any way, but i am using the latest build of windows 10 Version 1803 and build 17134.112. I'm also not sure if it's linked to another issue i have on Skype which entails me being able to see/hear people but Skype cannot access my sound card apparently so my mic/cam do not work via the desktop classic version. All drivers on my Logitech C270 cam and H600 headset are up to date also. Thanks in advance.
