It's because of an engine change in IwD:EE (probably to fix the bug with Dragon Disciples getting more CON each time you went into the Skills screen), and it causes you to get stuck at the "Select Cleric/Druid spells to memorize" screen since none are actually available to pick. My recommendation would be adding a dummy spell and later remove it with a .spl on the CLAB file. The component that causes this is the spheres one (the last one, designated as 1000).
EDIT: actually you can get past it with just pressing Enter/return… Seems like there isn't much need for a fix (maybe an updated string to say that?).
EDIT 2: still, you don't get to memorize the spells. :\
