Hey I've tried exporting my file a multiple of times now and even over night and it just stops exporting at 74%. I've tried uninstalling and reinstalling as well as clear caches. Nothing worked. I bought the licensed version to see if it would work and it still stops at 74%. What I don't understand is that I was able to export it previously like a day or two ago but now it just won't export. HELP!
