It appears as though MS has retaliated in relation to all of the freely available MSDNAA downloads that NON-MSDNAA members are downloading. There seems to be a new method of encryption of the SDC files and the result is no-one seems to able to unpack the joined output sdc file. I know that "imagi" is working on a newer version of his unpacksdc that will hopefully overcome this problem. BUT MY QUESTION IS: HOW/WHAT PROGRAM DO STUDENTS/ACADEMICS USE TO JOIN AND UNPACK THE SDC FILES THAT THEY DOWNLOAD FROM THE MSDNAA SERVERS??? AND WHY HASN'T THAT PROGRAM BEEN MADE AVAILABLE TO ALL US LEGITIMATE HACKERS???
