Red X On Tray Icon Appears On WiFi And Audio

I am having a problem. What happened was i tried opening a software called Pokemon Revolution online. People call it a client. When i did, it crashed and became "not responding." So what i did was held the power button to force restart it.

Now, when it restarted it (Im using Windows 10 on an Atheros Asus netbook), there was a prompt telling me that a file called system32/somethingsomethingsomething/Desktop cannot be found. And the desktop looks like it's been cleanedexcept the sole Recycle Bin icon. The wallpaper got retained though.

And so i restarted it again. This time, my desktop got restored to everthing, except that 2 red X's appeared in two icons in trays: the wifi and the audio. The audio i can deal with by troubleshooting. (Although it returns after 10 minutes or so). But the wifi is more pressing. The thing is, when i hover the cursor in the wifi icon, it shows me that it is indeed connected because i can see the wifi name. Oftentimes, it just says "Identifying... No Internet Access."

Another weird thing is that The wifi symbol used to be three curved convex lines, right? However, when the red X appears, the wifi icon becomesa rectangular image of a monitor. I cannot connect to the internet or use my audio after the crash.

Other details:

> when i restart my netbook, the wifi is okay. It shows me the regular three curved lines. But when the desktop is done setting up after i log in, it reverts back to the error.
