Why did Microsoft Visual Studio Commynity end after 30 days?

Question

Electronics

I put the studio, tore it off "once every 2 months" and suddenly she says that the trial has expired, give me the keys.
What are the keys? She's free!
How to fix it?
PS: studio 2013.

Answer 1

Microphone wires - yellow and red on top connect directly.
The remaining ones - 3 on the left and 4 on the right - headphone wires. Connect them like this:
Yellow on the left - on yellow and green on the right.
Green on the left to red-orange on the right.
Blue on the left to blue on the right.

Answer 2

you probably need to log in with a Microsoft account in VS itself and request a key renewal.
