I doubt anyone has successfully gotten 1.8 to work yet. I think OP has removed the the download that he put up do to some missing files and whatnot, so when he puts it back up, he will let us know, then we can start downloading it.
It all turns out white for me too, however if you click on the box area that you make your selection, it shows a drop down box with all the things you can select from, just choose one.
Hey OP, would it be possible to set the server up to be able to detect if someone is using the first, corrupt download of 1.8, and if detected force an update that downloads all the files that were missing from it, and then afterwords, download the updates that were added yesterday?
