Did you update the application first? The latest is 3.0 build 1008. Which version are you using?
If you delete the data folder, restart the app then check for database updates then it should redownload them.
The server does seem really slow but it is working still.
Found the problem, the build 1001 you have linked in the site news it's incomplete. I've downloaded the build 1004 from the download archive and then updated, after that all OK.
