Edu blogs theme sign up page

The sign up page issue.....
Now. I dont know if this is my error or if it's by design that it does this, but seems like it would be an easy fix for someone Thats knows what they are doing.

When there is a mistype in the sign up page ( I.e password doesn't match, email address is invalid)
And you press submit. It tells you what you did wrong BUT it's in plain text instead of large red noticeable text.

So I have people getting frustrated and not signing up because they don't notice the black tExt that's telling what to do to fix it.

.????? Please help as soon as you possibly can I launch tomorrow

Extra info. My edublogs theme is running on 2.1.3 if updating would fix it I'll have tons of new questions! Lol (I've had a lot of the graphics changed and moved and ofcourse wouldn't want to mess that up)
