hello if u are asking how to use the schematic u etered in ic 5.141 in ic 4.45 .its is simple.just add the library files oof the design in ic 4.45 into ic 5.141 using the library path editor.thats all.both versions are fully compatible both forward and backward compatible.
Which data are you talking about ?
Layout or Simulation..
I can help on Layout side..
Just reset your ICFB path to 4.4.6 and restart..
