What does "it does not work" mean?
Sorry for poor explanation. When I finish with the last digit of the serial number, a red X is at the end of the last box, instead of a green check mark.
So, the system shows that my serial number doesn't work/isn't valid/etc., so the only option is to check the 30-day trial box.
Then you have an invalid serial number and nobody here can help.
You’ll need to contact Adobe directly for assistance.
Just got through to them (sales).
The guy said that my serial number is still valid, and checks out with my email address. Since CS3 support just ended a few weeks ago, he said there was nothing further he could do, but he did give one suggestion:
He said it was possible that the version does not work 100% with my newer computer (MacBook Pro using Maverick 10.9.4). Thus, the "limited version" that goes with the 30-day free trial might work, but the full version might not. This didn't really make sense to me, since I would guess that the program would allow the serial number and then crash later were that the problem.
In any event, product works fine on iMac, works fine (as far as I can tell) on MacBook, but in 27 days the latter will stop.
Could be the licensing doesn’t work on Mavericks. CS3 it unsupported so you’re on your own, anyway.
