Ok for anyone using XSI. If you have been using different projection maps and have froze them and now you have made new UVs but they keep defaulting to the old UVs all the time, just select the geometry that has the UVs then click on the clusters button on the main control panel on the right and at the bottom you will find all the various projections on your object. Just select what you don’t need anymore and delete it. BINGO.
This only took me all day to figure out. Exciting. Now you two can become a professional XSI user! ;P
