I am currently uploading a fixed release for this particular issue. If anyone thinks beta3 is a lost case, I can relate to that, but the show stoppers seem to be fixed for now.
In about 15 minutes you will be able to download the fixed release. If you want to see what exactly has changed, I have committed all changes/fixes to the release branch.
