Issues publishing project to video

Hi, I'm looking for an E-learning hero :(

I have issues publishing a storyline project to video. The project is composed by a screen recording about a software process. I have 43 slides with a 5:20 minutes long project; it weighs about 48 MB.

I have updated both, Articulate and Storyline, and followed the correct steps for publishing to vide,  but the project is in process of publishing for more than 4 hours and it doesn't finish.

About a month ago, I made some projects doing exactly the same than now and had no trouble publishing to video.

I need help to solve this situation because have to record and publish lot of projects like this as part of a training for new software usage in my Company.

Thank you!
