Premiere Elements 11 does not have an export to Adobe Revel in its Publish+Share section as does Premiere Elements 12.
So for Premiere Elements 11, I would be guided by the April 23, 2014 FAQ in the Adobe Revel Forum.
You could try saving the Timeline to file via
with one of the .mp4 presets
Then you would upload the file to your account at Adobe Revel.
For further information about export to file your Premiere Elements 11 Timeline, I would need more information on your Premiere Elements 11 project settings and the properties of your source media. Video uploads to Adobe Revel can be problematic, so you might want to post your Adobe Revel uploading type issues in the Adobe Revel Forum. We, here in the Adobe Premiere Elements Forum, can help you with your Premiere Elements 11 export to file settings for that project.
We look forward to further details to assist you in your project.
