Lo he intentado varias veces y es imposible, siempre pone procesando. También lo he intentado en Facebook y tampoco me deja. Tengo la versión de prueba.
You should be able to export to YouTube or Facebook without an issue on the Free Trial. I will post some useful links below on how to do these things so you can check against what you have done. Also some common issues and fixes.
Also please bear in mind that the upload is a 3 stage process, first the video is made, then you sign in, then your video is uploaded. If you press the X at any point this will cancel the upload. You will see the below when it's uploaded. Only click the ticks, if you click a X it stops the process.
If you are still having problems after that it would be useful to know at which stage the process is failing? Are you getting as far as putting your YouTube/Facebook password in? Is it failing before that and at the same point each time? If that's the case which element is on screen at that point as it is likely that there is a problem with that element.
