Default [Q] Apps not being transferred to SD Card!

Hello Im having a very serious issue with my phone. I cant move apps to my SD Card for some reason. my phone is rooted and i tried using app2usb or whatever its called but still no luck i know my phone can read the SD because i have songs on it and my music player can play the songs on my SD but i just dont understand why its not letting me transfer apps nor letting me install apps into it. PLEASE HELP!

I have a Samsung Galaxy S 4g from tmobile with custom rom, Cynogen Mod 9 ICS. I also have a 8gb SD card

I have also tried deleting smdl2tmp1.asec but i cant find that in my phone nor my SD Card
