I know this is a very big bump but I have a problem relevant to this thread.
When advancing in red wizard of thay class I do not get any new spells. But your uploaded character has a lot of spells. Am I doing something wrong?
That depends, what is your base arcane spellcasting class? Wizard, Sorcerer?
Unless the prestige class specifically says that you gain new spells known when you level up in that class, like Cerebremancer, then you will only gain an increase in spells per day and caster level for your base class.
If it is a Wizard, then you have to learn your spells from spell scrolls, if it is anything else, then you need to level up your base class to get your spells.
Hope that helps.
