bad stitch

as a user of ptgui for a bunch of years, i recently made the switch to Panoweaver based on the trial version correctly stitching an 180x360 that I was unable to build in PTG. Now following the purchase, the app will not correctly stitch the image. since I'm new to the app any help would be appreciated as the client probably won't accept the pan with the EasyPano logo all over it. Thanks
