Still noting some erratic issues on the development demo. @stephenwaite, that error is because it was unable to download the translation file from another appliance on my server. Should get it worked out soon.
@MatthewVita, regarding speed, since there are many appliances going on the server, the server seems to give priorities to the ones that are used. So, if you use the development demo for a couple minutes it should speed up. Of course, using a server that is using Ubuntu 8.04 with VMware server version 1 is likely not helping things.
