I am fairly sure the issue I am experiencing getting the demos to run on my server is due to the server being a load balanced linux server.
The error I get when running the demos occurs once the progress indicator gets to 100% and is as follows:
Unable to find file de604f2a-e96f-c0bc-3cda-56ac3ce1b27b in /tmp/uploadertemp
Hopefully you have encountered this problem before and have a solution for dealing with load balanced servers as it would I would prefer not to have to switch to a different hosting package.
I have emailed support with the FTP details of my site in the event that this will help them deal with the problem.
