Default [Q] HELP Installed a new rom and it hid half of sdcard?

So I installed the maximusHD 10.0.0 again because I was having problems with the liberty.

When I boot up and go to the folder with my apps in it, theres nothing in there.
I don't think it actually wiped everything because in the free space there is only 1.9gb which is where it was when I installed it.

unfortunately I did not back up my sdcard. however I have installed this rom many times before without it wiping my sdcard.
My phone is s-offed and I don't even know what hboot is currently on there. I think its a newer one but i don't think that matters.


I don't even know what to search for. Any help would be appreciated.
