DAW software not recognizing Nanokey in Windows 7

[rohand87]

Its about a week I got my Nano key. I installed the driver version 1.12 and it was working fine. It was until yesterday that I download driver version 1.13 and Nano Kontrol Editor. After installing driver version 1.13 and and Kontrol Editor the Nanokey stopped showing in MIDI device list of all my DAW including m1le and Kontrol Editor right after installation didn't detect my Nanokey.

The latest scenario is, I have tried the following with both driver versions (1.12 & 1.13) and still no gain:

1- The "Install KORG USB-MIDI Device" in "KORG USB-MIDI Driver Tools" and it says "Driver Has Been Installed Properly"
2- The "Uninstall KORG USB-MIDI Device" in "KORG USB-MIDI Driver Tools" detects the connected Nanokey. I have tried removing it also uninstalling the driver and re installing it (both 1.12 & 1.13)
3- Tried running the Configure Utility. It also detects the attached Nanokey

P.S: Please don't give me solutions like changing USB ports or trying without a USB HUB. I've done all of this stuff. Recommend me a proper fix.
