That has nothing to do with your version mano. It means that you have some polys with more than 4 points. You should figure out which ones are (with your statistics box) and split them. You may want to try to merge points also, just in case something messy is floating around. It could also be that you have some unwelded points.
Why it wont work at all I don't understand. It should work, at least for the polys with 4 or less vertices. Hit 'o' to check your options and make sure the patch divisions are at least 3.
Hope that helps.
