I had problems before with setting a video to the map, solution: Delete file "avcodec." The file keeps returning anyhow. The problem now is that ehrn i want to upload the beatmap it gets stuck on "Creating Package" and I cant click anything in that window. When i press cancel it says "Error during upload. Couldnt create your package, make sure you some disk space free. Which I have? Then it says video playback failed, might be due to missing dll files. Please help, thanks.
