Every new device gets error 31 in device manager?

I've had a problem with the internet so I decided (foolish decision) to remove the network adapter s driver (Realtek PCIe GBE Family Controller). After I removed and connected the wire to the pc it shows the adapter in the device manager net adapters list, yet there's a yellow exclamation mark on it. It says error 31 and when I try to reinstall the driver from disk it says it can't find the driver.

I've tried to connect my iPhone to the pc and use it as internet, yet there's an error 31 on it too.

What can I do? It happened few days after I cleaned my pc with cCleaner, maybe it's related?

Still not receiving texts from someone I unblocked?

Since apparently the background story is important… I got into a fight with someone about 3 months ago and I blocked them from receiving texts and calls on my phone. A couple weeks ago I unblocked them and started mending the relationship. However I'm still not getting texts from them and I know I they've been texting me because I saw the persons phone and they have been sending me texts in a group chat. I have an iPhone 5s and in my settings it says I have no one blocked. How do I fix it so I get their texts again? Has anyone else had this problem?
