Cannot Mount Ext2 on Link2sd

I installed MiniTool Partition on my PC, and partitioned my 8 GB FAT32 SD card to a 6GB FAT 32 and an EXT2. But then when I installed Link2SD on my android phone, I choose ext2 as my 2nd file extension and then it said, "Mount Script Error" How to mount my Ext2 file extension?
