As of 08/01/2017 support is no longer offered for DOIFD, free or pro versions. Support is available via our knowledge base.
Why? A couple of reasons, but it all dwindles down to time. I have none left. My options are, shut down DOIFD completely or eliminate support. I decided to try eliminating support first because there are still quite a few folks out there that are benefiting from the free and pro versions without the need of support. By giving up the support, it will give me the time needed to work on enhancements and upgrades.
