CS3 Activation Problem workaround?

Hi, I work for a small private school and I need to reinstall our site licensed copy of CS3 Premium on our desktops.  I have been able to install just fine, no problems. I have a proper serial number and that part checks out, no problems. The problem is that I cannot activate the software.  I have talked to Adobe support a number of times and what they are telling me is that the activation server at Adobe is no longer running since the product is too old, so that is why I get the error about the server not connecting or the error saying that I have used all of my activations (impossible, since I have a site license for the product).

You might suggest the Offline Activation, but, alas, that is no longer available as well or the phone activation.

Support basically told me to go to the forums and hope for a workaround.  I have looked through many of the forums, but I only get the answers that recommend things I have already done above. 

I am looking for one of two things:

1) An activation code that will work with my serial number on multiple computers (again, I have a valid serial number, that is not the problem).

-or-

2) The software will run just fine for 30 days under the non-activation mode.  So, if someone has a way for me to delete this clock and either never have to worry about it, or just re-set it every 30 days, those will both work.

This is installed on a Mac desktop running 10.9.5, and, it runs just great on it!

Thank you for any help you can offer.  Again, I am at a small private school and we just can't afford to go the new monthly pricing scheme at this time.

Thanks again.
