Xojo 2013 Release 4.1 is now available for download at http://www.xojo.com/download. As you may be aware 2013r4 was removed due to a bug that was causing a crash upon launch that was unfortunately not discovered during beta testing. We worked through the night to fix the issue with 4.1.
If you did download r4, dont worry - your projects were never in any jeopardy, but we do encourage you to download 4.1 so you dont encounter this issue in the future. Unfortunately, these things happen and Im sure many of you have even experienced issues like this with your own software. Our top priority is to deliver a quality product to you and we appreciate your understanding and support.
