The file errors make me wonder if there is something wrong with the installation. Go ahead and run the troubleshooter (http://wiki.covecube.com/StableBit_Troubleshooter) and include your ticket number. I think you'll have to wait for Christopher to handle this one. I'm not sure what's going on.
That makes me wonder if there is a corruption in the installation. Do a search and see if you can find the service folder. Search for a directory called "ChunkIds", which is where your DB is stored.
