Default [Q] Rooting the phone

I have a Celkon A107 Android 4.0.4 phone. I rooted the phone using the interface programme mobogene.Then I have made partition in the SD card using the mini tool as per your instructions. I also installed LInk2SD and when I open the Link2SD the message "Link2SD unable to access root. If you have root, make sure that enable superuser" comes. Please help me to solve this problem
