I had Photoshop downloaded on a previous computer which has since crashed. When I downloaded the program on my new computer a pop up keeps appearing. "Serial Number is alreday in use by the maximum allowed computers. You need to deactivate another computer to use this product." then it give two options. "1) Retry activation. I have already deactivated one of my computers. Or 2) Provide a different serial number." not sure what to do or deactivate a computer that has crashed with no chance of repair. Any ideas?
