For example, what your workflow up to creating the flow direction?  Did you do the standard operations of filling sinks? were you running this in Arctoolbox, did you expressly set the analysis extent and cell size in the tool within Arctoolbox or did you rely on default raster settings.  Grid expression is sometimes generic...sometimes due to a mistake in the processing steps ...

Read the link in detail regarding image formats, for example JPEG files are compressed image files. They support 24-bit color and have been a popular choice for use on the web because JPEG file size is often substantially smaller than many other image formats. However, the JPEG compression algorithm is lossy and is not recommended for most map images, as line drawings and text or iconic graphics become blurred by compression artifacts. Thus,  PNG is usually a superior format for map images. JPEGs exported from the data view in ArcMap can be generated with an accompanying world file for use as georeferenced raster data. ...

If your DEM data are in a geographic coordinate system (aka GCS, longitude-latitude), I would project it to a projected coordinate system (Project tool, to UTM) prior to constructing the TIN.  I would ensure that the polygon file is projected to the same coordinate system as well...then try using the tool ...
