I'm sorry to hear you are having issues getting started with our extensions, but if you could tell me what you are trying to accomplish i can direct you to where you can find our documentation.
You can find most of our documentation by going here:
and selecting the product.
In regard to documentation not being updated, if the documentation is not up to date it is because we still support older version of the extensions but for the most part documentation should sill work with newer versions as well.
In regard to the errors that you are getting, if you could please post back with screen shots with the errors you are getting and i will assist in resolving those errors.
