Digital BW, The Print

i'm using MISS inks variable tone set on an epson 1280, windows 98, 
photoshop7 and only the 2 curves "...c14 " and ". . .nc15" will load- 
all the remaining ones won't load. are there versions that will work 
w/ PS7? if not, is there a work around? the only other edition of 
photoshop i have is 5.5 elements- can i edit in PS7 and bring into 
5.5 for the curves? if so, how? thanks, craig
