Cubik Studio

i try to enter the license information but it doesn't work
- my old license information is BDC-XXXXXX
i tried BCS-XXXXXX but it doesn't work too

i really want to use BDCraft because my resourcepack version is 1.8 and Cubik Studio are not support with 1.8 version
Sorry for bad endlish
