Do you have a stacktrace? I guess it's because of the missing request parameters width, height or SRS. Properly there should be a WARNING message (getMap or getCapabilities) with the requested URL. Please check these URL's.
Right now I'm not sure, whether the width and height parameter should be equal and should always have the same value (256 or 512). Could anybody confirm that?

Hi Frank. I'm running into similar issues. If possible could I see
what changes you have made?
I've only got as far as putting "TILED=true" back into the request in
appears to strip tiled=true from the request. Now uDig will send a
sensible request but the WMSC
wizard does not progress.
