Hi Bill,
No doubt Maximizer would have told you that the CRM 11 release isn't supported in Windows 10, so that's why they're probably suggesting upgrading.
We could 'try' to trouble-shoot the problem for you under hourly chargeable consultancy, but as it's not officially supported in Windows 10 we cannot guarantee a successful resolution.
If this is something you'd be interested in, then please reply to my business email address (paul.coughlan@advoco-solutions.com) and we'll continue our discussions in private?
Regards,
