DownloadPlus is overriding some Magento Core Classes. So when experiencing conflicts with other Extensions, or having lost store customizations with DownloadPlus being installed, these are the Classes DownloadPlus is overriding from the Magento Core:

Mage/Downloadable/controllers/CustomerController.phpPisc/Downloadplus/controllers/CustomerController.phpTo subclass the related core class.
Mage/Downloadable/controllers/DownloadController.phpPisc/Downloadplus/controllers/DownloadController.phpTo add the DownloadPlus Terms of Use and Tracking functionality.

In case of Magento Core classes overridden by other extensions, or own customizations, be aware that you might need to consolidate these changes into one of these classes. To keep the DownloadPlus functionality in such case.
