Help, I can't download some things from maemo, such as the maemo mapper and periodic table (for chemistry).
It says that I am missing some packages, mainly libgdbm3, and a few other things
I don't know what is happening, other files I download are working.

oh, and also when I try to move things from my computer to my 770, it doesn't show up when I try to run it (music, pdf, ebooks) It says the space has been taken up but it doesn't show anything when I try to find it
