Register Error

[Tequila]

On both Little Legend and Crystal Hollow I am finding that users cannot register.

I made changes to the form for CH, but haven't for LL, instead of registering properly, it redirects to the login.php with the following error:
Something was left blank. Please try logging in again.

Any ideas? I'm using 1.2.4 for LL and 1.2.3 for CH.

umm perhaps the database structure of table prefix_users aint compatible with Mys v1.2.x's?

That's what I'm afraid of. I used all new with Little Legend, but did make changes in Crystal Hollow. Looks like I'll be playing with code tonight though. 3;
