Blow Up Plugin Photoshop

We are trying to automate photo resizing using Blow Up plugin for Photoshop. We are using the trial version of Blow Up. It causes a window to appear that says continue trial. This seems to disable our Macro. We have tried to record clicking the box. It doesn't work. We are trying to ensure that it will work with keyboard maestro to resize multiple images and save them. We want to make sure Keyboard Maestro and Blow Up for Photoshop are compatible. We are new users to Keyboard Maestro and may be doing it wrong. Any suggestions?
