Maybe it's better you give us the lines you are using in your program to 
read and write the line. Then we should be able to see where the bug 
sits :-)

Did you try the File functions to do this? These should work without any 
headache: File.Read and File.Write. Look them up in the help.

If you prefer to open a stream for file writing, there are more things 
to be considered, best is you give us an idea of what you have written 
there...
