As usual, Reflexive.com has updated their registration information on new downloads from their site. This prevents the previous Reflexorator (v1.2) from working. This new version cracks all Reflexive games released at this time (Jan 2009) and should continue to work until at least December 2009.
There are two options when running this software. First, you can Patch the file EXE file as you used to do in v1.2, but that won't work for new downloads. The other option is to Unwrap the file. To do so, run this version of Reflexorator and then select the EXE file for the game that you're cracking. It will then ask you for a filename. This filename is the cracked file that you'll use to run the game. By default, it will be the game's filename with .Unwrapped. added to it. Note that this will mean your desktop shortcuts will point to the wrong file. You'll have to create new shortcuts or change the current ones to point to the new unwrapped file. Once done, your games will play as full versions.
