The link for download SDK for version 7.3.8 is not working.
There is something strange with the size in the page:
Module SDK
Ignition-ModuleSDK-7.3.8.zip (Size: 0 B)
Version: 7.3.8
If I use the link “http://files.inductiveautomation.com/release/build7.3.8/06-18-2012_12_54/Ignition-ModuleSDK-7.3.8.zip” the response is a xml with the text “Access Denied”
