SDK for Sage 200 CRM 7.1g

Hi,

I have to do customisations for clients using the integrated version and was wondering if anyone knew where to get the SDK for Sage200 CRM?

I got the SDK for CRM 7.1 from this site for working on standalone CRM but I noticed there was a note on the downloads page that the SDK was not for use on any installations which were integrated with Accounts.

The note said to try the sage support page so I logged in there and looked in the Sage 200 accounts downloads but couldn't find it. I saw a section on CRM but it just had a few papers and said the majority of downloads were available here.
