Hi Michelle,
Just a longshot: check what the decimal separator is in the .prj file.
Then check your regional settings for the default decimal separator on
your system. They must match, or ArcGis will not recognize the projection.
As for the projection, simply go into ArcMap, import some point,
polyline etc. data, change the projection to UTM nad 27, copy all the
specs (datum, false easting, meridian, etc.), then use project wizard
from ArcToolbox to physically reproject your data. You will need acces
to Arcgis Workstation though.
Hope this helps,
Dan CRACIUN
