Regarding the ability to not memorize spells, there are two likely answers (leaving out the possibility of tech issues):

1) You have a specialist mage that cannot write spells of those schools.

2) Your character's Int is not high enough.

You need 18 Int to cast lvl 9 spells, and iirc 16 Int to cast lvl 8 spells. If your character has less that this, you may have serious problems rectifying the situation. There are very few items that raise Int permanently, which is what you would need. If your Int is indeed the problem, I would suggest using Dalekeeper to raise it a couple of points.

I'm not sure what you mean by the second part of the post; "[not] been getting any automatic spells memorized in my spell book". Do you mean that you are not gaining spell slots of the higher levels? That would be an indication of a low Int.
