Windows 10 update deactivated my CS3. Support won't help me.

Hello. My pc did a large Windows 10 update last week. After the update, I opened CS3 to find it had been deactivated. I clicked on the (activate online option) as always and it said no connection. I clearly have a connection but it wouldn't activate. Over the weekend I lost use of my software. I contacted adobe through chat last night, after waiting over 2 hours for an agent. Simply put, it was a nightmare, as was todays telephone conversation with support. In the chat last night, the man wanted full access to my computer. All I was asking for was the authorization code that the software was now asking for. He had me uninstall my CS3 and reinstall from a link he gave me. He also had me request a new activation code. I did both, and no change. It says invalid code. I told that to the man on the phone this morning and he just tried to sell me the new version, and said he couldn't help me with mine, because they no longer offered support for it.  I've always had a licensed version of CS3 on my pc, and it wants a new code. He refused to assist me with this after another hour on the phone with him, and told me to search the forums for an answer. I could have never imagined after all that, that he wouldn't just simply give me a working code. I'm stuck now, and I'm losing money every second that this software won't work.....can anyone help? I simply can't believe this is the support I've received from a product I purchased and have used for years.
