I am using Mustang PE2 builder for my ATI 2009 and DD 10 plugins. So far had not problem with ATI 2009 version upto 9709. But with all the version after 9709 , I am getting error "" the exception unknown software exception (OX40000015) occurred in the application location Ox4b64b4" Click OK to terminate the program. ie I am able to create the ISO and when the CD is booting and when I click the desktop icon on ATI 2009 this error is displayed. I tried both in WIN7 and XP Home edition. Both given the same error. Kindly advise and thanks in advance.
