If you're trying to cast a spell off a scroll, is it above your level? I know arcane spells can't be copied if they're above the caster's spell casting capability but I can't remeber if the same applies to casting from scrolls.
Also, is your WIS high enough to cast those spells? It needs to be high enough so you can get access to those spells e.g. 14 WIS would allow you access to 4th level spells but not 5th.
Glad you found your CD key
