I tried to use the PowerWindows module with LoadModule. While LoadModule didn't report any error,
LoadModule does indeed give an error. You must not run it with >NIL:, then of course you don't see the error message.
The Blizkick module does not work with LoadModule because it does not contain a resident tag. That's what the error message says.
PW does work perfectly with a modified ROM used in WinUAE. No need to use Blizkick.
