Oh silly me, forgot to include that in the previous reply XD.
If on Windows, go to Start, type in "add or remove programs", then navigate down to PixInsight, click "uninstall", then press "yes" if prompted by Windows, then the PixInsight install/remove window should pop up.
Click the "repair" button and it will go through and repair the installation. Once that's done, just reopen PixInsight and go to the repositories, manage repositories and check for updates.
Hopefully this fixes the EZ Processing Suite errors!
