Why can't PodTrapper use my SD card?

[JayAaroBe]

I have the Droid Bionic and I bought the full version of PodTrapper (PT). When I install it, there is no way for me to have PT use the microSD card, instead it is using the internal memory. Even if I go into PT's storage settings and try to change the folder path, I can't navigate to the microSD card because the "highest" directory I can go to is /mnt which is on the Bionic's internal memory. I cannot go "up" to a higher directory to select the microSD card. I have tried uninstalling and reinstalling PT but that did not help.

Please advise, if someone can help me get this working properly I would greatly appreciate it. Thank you
