SD card not Connecting via USB

Hi all,

I got the MMX A63 mobile.

From today morning, i am facing a strange issue.. When i connect the mobile via USB to my laptop, the SD card is not showing up. Only the internal storage shows up, and in the mobile, i can still access the SD card.

But if i connect via MTP protocol, i can access the SD card too..

I rooted the device a few days back.

Any suggestions??

Also, while connected to the laptop, the app/games installed on the SD card do not show up. But, after disconnected from the pC, they still dont show up..

i took out the SD card from the mobile and connected it via a card reader, and its working fine, though it does not allow to write files..
