HELP!!! Having ASTRO issues and I cant figure it out

A little background: I had to warranty my Galaxy S because the USB port was all mucked up. I was trying to upgrade to FROYO and couldn't connect. So, My device was exchanged no problem.

The problem:
I downloaded ASTRO and backed up on my files on my SD card...or at least thats what I thought. When I opened ASTRO the very top file read "/sdcard" so I assumed thats where the apps were saving.

So i got my new phone and re-downloaded ASTRO from the market. When I opened it, however, the icon at the top read "/mnt" thats all. No files, no apps, no nothin!

I really have no idea what to do. All i want is to be able to access everything i saved from my old Galaxy S and put it on my new one. Anyone have any ideas?
