Is there a way to get V11.2.9.8947 old build?

I have this version installed on main computer and it works perfectly, but when installing new version on other computer some functionality is lost:

In 11.2.9.8947, "External #" field is mapped to ebay item number, and I can't get it to work in any of the newer versions. In those versions, "External #" just shows up empty, "External Transaction ID" is blank, and "External ID" shows a bunch of gibberish, possibly the eBay transaction record.
