Extract Data Task errors

Hi'ya,

I am trying to run the extract data task. I have published my map. I fill in the values with a raster layer. It returns with 2 errors...

Failed to clip layer <layer name>
Extension is invalid for the output raster format. Please verify that the format you have specified is valid.

I have tried only clipping an area of interest and adding that layer, not clipping, or clipping and adding a raster.
I have tried changing the name of the output and changing the extension, including .tif, .img, .zip and leaving it blank. The output defaults to a .zip format. I have tried just using the default value. Nothing seems to resolve this.

I am open to suggestions as to what I can try. I dont really care about the output. All I need is for this to run once so I can publish it to arcserver. I wonder if I publish this output with a warning if it will work? It does say completed successfully, even though I cant view the file.

Any help is appreciated. Thank you, in advance.
