Anyone have the Sage 50 2019.3 SDK?

Hi,

I'm currently making a third party app for a client using Sage 50 Quantum Accounting 2019.3(26.20.0.2) but I have been given a 2019.0(26.0.0.1) version of the SDK, which is not letting me use it:

Message from recources (english version):

I've looked everywhere, no sign of this version to download, all links to 2019 versions of the SDK are broken. I even contacted the support and the only thing they gave me is the same broken download link:
https://cdn-dlm.esd.sage.com/Sage50CanadianEdition/18307/Sage50SDK20193.exe

So this is my last hope, that someone will see this thread really soon and they'll have somewhere in their server an instance of the 2019.3 version of the SDK and they'd be kind enough to email it to me!

Thank you for taking the time to read this and have a good day,
Émile Roy
