As for you not being able to cast any level 9 spells. One thing is that you're only level 17 (and with the Throne of Bhaal expansion pack can become level 40!). Even if you're with a party of six you can bump into the Shadows of Amn XP limit, because there are so many quests to be done and so much XP to be earned.
IF this is not the problem, then it could be a bug (but I'm a n00b at identifying them). Nevertheless it's a good idea to install the patch and the Baldurdash fixpack, because they WILL help you out when you're in trouble because of a bug.
You can find both the patch and the fixpack in the "FAQ's" thread on the top of the page. Dundee Slaytern is the author of that thread.
