I have tried for 4 days now to upload a video of mine but for some reason everytime I do it either finishes uploading it only to take me back to Step 2 or says I have already uploaded the file. I know it is not the video itself as I've tried others to no avail. I have recently changed my email address under my profile (and already went through the new confirmation email).

Please help, I have no idea what's wrong with it.
