My old computer, which had CS3 installed, crashed and I had to replace the computer. We re-installed the CS3 program on the new computer, and the prompt calls for a serial number, which we do not have. I obtained the original CS3 while registered as a student at Dixie State University. The Coupon Code is: HL1A-003B-L2AO. There are only 7 days remaining on the new trial period. I e-mailed Adobe requesting a serial number several days ago, but have not received a response. How do I secure the serial number? Rollo B.
