Default [Q] Link2SD

After I install the Link2SD and run it the 1st time, it is asking for the root access, but I am not getting the file system screen with choices..!
I even tried to make it happen manually, buy choosing the "Recreate mount script" from "More" menu, but it gives this message : ":device not found" Make sure you have two partitions on your SD card and both are primary,, Which I have !
I have created 2 partitions: one of them is a FAT32 and it is Primary partition and the other one is ext4, which is a Primary partition too !! I create those by using the "mini tool". What's the problem?
