Now I'm having trouble uploading a video. I upload, can't pick photo as the last step for some reason and can't press Finish and then says I can't upload without a video, then I have to go back to uploading, then press next and this repeats. I already have a channel made, this is the first video I'm trying to add to the channel

Hi. The system is accepting only .mp4 video. If you have other type, just convert it and everything should work perfectly. I have uploaded many videos on my channels already and it's been working well. Regards.

Thanks
I actually had to convert it from MP4 to wmv.
I uploaded my first two videos!

Great! I am glad it worked :-)
