Uploading pez from desktop prezi to web

Hi..

Is it possible to upload the prezi to web without using the desktop version?
The option in desktop version is not working .. the prezi stops uploading after 2%.
What I tried so far..
1. I uninstalled prezi desktop
2. removed all browser history
3. Installed the latest prezi desktop software.
4. Still facing the same problem.

Any solutions?

One more question... Why there is no option to upload a pez file in web? Is it something that is purposely not given or you plan to add this feature later?

Thanks
Prashant
