help with this

I have a problem with this code, it does the following:

Download the file archdone.lst by ftp and after it finished it opens the file and read it line by line.
The problem is that after finished downloading, i can't read the file. The ftp works fine but when i try to read the file is like it was and empty file, but in reality the transfer was ok.

Help with this please!!!
