Scribing Failure - Spell ID Out of Range

[Persea]

I don't know what's causing it, but I followed CaveDude's instructions for making a new server, using both his PEQ Installer and the Upgrader, and when I finally got it working everything looked like it would be juuuust fine. But then I made a spellcaster...

I start with two spells in my inventory, and no matter which one I scribe, I sit down and it says:

Beginning to Scribe

and then just a short while later in huge red letters,

ERK Can't scribe, 'Spell ID Out of Range.' What in the world do I do? My game is completely unpatched, but assuming that it wasn't and that anything in the world could possibly be wrong, what could possibly be happening here and how might I go about fixing it?

After it fails to scribe, the scroll is stuck to my cursor, I can't open my inventory and I have to quit to fix the problem.
