GUI_DOWNLOAD APPEND='X' doesn't work

Question

Hello,
I seem to have a bit of a strange problem. My report uses GUI_DOWNLOAD to download some data. Then it uses GUI_DOWNLOAD again to append one more line to the downloaded file. The problem is, I have changed my PC and appending stopped working. The target file is just overwritten and not appended(as topic states, I have used APPEND='X' ). Looks like it has something to do with operating system. How can I solve this ?
Thank you,
Bart

It's the same file. Its contents are erased and data from last call to GUI_DOWNLOAD is written into it. Well maybe not OS oriented but definitely not hmm 'code oriented'.  I was writing the report on my old PC, used it many times and it worked fine. Now after moving to a different machine it stopped working. Paths are ok, behaviour of GUI_DOWNLOAD is bizarre. I've uncommented all the exceptions but sy-subrc = 0 so still no clue.
EDIT:
What's more interesting, I've moved the same piece of code to an external report. Executed it and it worked fine.
