I made some changes to the Qora codebase and added a pull request here
https://github.com/Qora/Qora/pull/11. This should recreate the data folder automatically if something went wrong. I think that should help most newbies.
Great I will check it out.
I am also going to work on the other issues that were reported.
If you are getting errors or crashes please create an issue for it on github.
