Thanks Max, your comments above sound promising.

@ hartwellj - I don't really agree with your last comments. New modules release was always with newer cart versions in C4 and XC5. Imagine you are using XC 4.5.2. New module is released for XC4 based on XC 4.7.4. Do you really expect the developer of this module (whoever that is) to release it for all XC versions even for 4.1.x? (Oh yes I have clients still using 4.1.8 and not thinking about an upgrade at all)

You can't expect every new module to be compatible with all XC versions. XC 5.1.x is old and it is understandable new modules will not be coded for it. But you can always ask the developer of the module for custom adaptation of the module to your cart.
