SCREENPLAYS PAST DUE

I was not able to completely finish my screenplay  the Friday before break because I had some problems in the end of ACT 2. However, when the bell rang, well before it rang, I downloaded the Celtx app on my phone and finished up[ the rest on my phone since our computer at home is currently not working properly. I have finished the script now I finished it on tuesday of the break but now i have the problem of  figuring out how to get the script from the phone onto the computer and print onto a hard copy since the app crashes every time i try backing it up online I have to copy and paste from my phone and email it to myself so that i can then try to download it from the email and into Celtx on the desktop.
