HCK 2.1 QFE 008 introduced a bug that has had a widespread impact for customers trying to re-package or merge an .hckx package.

How do I know if this bug is affecting me?

If you’ve created a package with QFE 008 and are attempting to re-save or merge that package, you might encounter this issue. Failures will appear as this HCK Studio exception:

System.ArgumentNullException: Value cannot be null.

Parameter name: inArray

Help! I’ve already installed QFE 008 and I need to merge and/or re-package my .hckx files

QFE009 contains fixes for the packaging error and is available on the HCK download page .
