1089 – ActivInspire Resource Pack downloads as .zip
The ActivInspire Resource Pack file extension .as4a is not recognized by some older versions of Mac OS X. Occasionally, it renames the Resource Pack .as4a.zip, which means the file can no longer be imported into ActivInspire.
Should this happen, simply rename the file to import it. Locate the file, right click and select Get Info.
In the Name & Extension field, delete .zip from the file name.
Close the window.
You can now import the Resource Pack into ActivInspire.
