Closing a file with 
file:close()
or 
io.close(filename)
just prior to the file being read or written can't be accessed with write/read functions again because the file and its data is no longer in the memory stack. Any use of further I/O handlers after the file is closed will cause an error.

Judging by the error output use this piece of chunk 
local file = assert( io.open(filename, 'w') )
to re-open again the file or show us the bugged code so we can take a look what exactly you did.
