Hello HoneyFun,
Thank you for getting back to me. No problem for the timing, at all. I hope that your video game will go on the right direction and I'm looking forward to play it when it's ready.
Yes I've checked and it wasn't there. I finally uploaded it using the website itself and it worked. For the time being I'll be using that solution, so no rush to work on this, take it at your own pace ^^.
