Why won't my Lumia 520 charge?

My Lumia 520 wont charge

UPDATE: I SUCCESSFULLY FIXED THE PROBLEM, NOW IT WORKS


I have installed the new W10M build and everythings worked perfectly (and I charged my phone yesterday to 100%) but today I replaced my SD card and my phone isn't charge. When I plug my phone to charger it's booting up but i got the "Battery Critically low" message. I tried to connect to PC and a different charger but nothing happened. Please help me! (My Lumia 520 is 14-15 month old.)
