I'm using a riced 5.0.3 client with pol096.3

Everything has been working great and is very stable all but one thing. I use my own prof.txt file that just simply has less classes to choose from... there's nothing actually custom, I've just removed classes. The problem is when I go to create a new character, it will lock up at the "creating character" part. I'll check the console on the server and it will say, "invalid parameter". Here's the twist. If I exit out of the client completely, and try to create the character again, it will work. Also, if I'm playing with one character, then I exit (but not close the client) and then create a new character it also works. It's only the very first time the client is opened and a new character attempts to be made that I have this problem.
