I see on this page that IPA Unicode 6.2 is a MSKLC keyboard (written using Microsoft tools and not Keyman).
There is also an IPA Keyman keyboard and you can use the configuration tool of Keyman to install it.
Not sure why a Keyman update would affect the MSKLC keyboard. Maybe check the keyboard settings on your project (Project menu > Project settings > Keyboard…) to see if the keyboard can be selected for automatic switching.
